Collection Configuration

Feature Overview

Collection Configuration maintains channels, devices, and variables. It is the main GatewayRuntime entry point for connecting field devices, collecting point data, configuring alarms, and controlling writes.

Private protocol access

When there is no ready-made collection plugin but the protocol can be described using fixed requests, framing rules, and data offsets, please refer to Custom Full Packet.

Operation Steps

1. Open Development Configuration → Collection Configuration.
2. Create one channel for each collection device and enter its IP, port, or serial settings. Skip the channel only for plugins that do not use a standard channel.
3. Create the device, select its collection plugin, and fill in the plugin-specific properties.
4. Create one to three variables, verify their values, and then import the complete point list.
5. Select the device on the left, click More Functions in the device context bar, and use the Debug tab to read before writing. Export the finished configuration after verification.

For ordinary collection devices, use one channel per device. Share a channel only when the plugin manual explicitly supports it. DTU Service and Gateway MQTT are documented shared-connection exceptions.

First, look at the terminology

Terminology	Field meaning
Channel	Gateway-to-device communication link, such as a TCP connection, a set of UDP communications, or a serial port.
Equipment	A PLC, instrument, acquisition module, or logic device managed by a plugin. Ordinary devices should use their own channel.
Variable	A point in the point list, such as temperature, pressure, operating status, fault state, or control write point.
Other Channel Type	No standard communication channel plugins. Plugins do not require ordinary TCP, UDP, or serial channels; connections are handled by the plugins themselves or do not require external connections.
Cron expression	Timer expression. For routine on-site cycles, it is recommended to prioritize the number of milliseconds, for example, 1000 means 1 second.
RPC writes	external system or page backwrite points. Only control points need to be turned on; monitoring points are generally kept off.
StreamAsync	Serial port asynchronous read/write method. Maintain default when serial communication is stable; Adjust only when encountering issues such as blockages or untimely reads.
DtuId/DTU Number	DTU or Passthrough Terminal Number, used to distinguish which remote device is accessing.
Topic	Topic/path in message systems such as MQTT or Kafka, which can be understood in the field as the data channel name agreed upon by the external system.

Function Entry

After logging into GatewayRuntime Web, click the "Development Configuration → Collection Configuration" menu on the left.

Confirm Before On-Site Configuration

There are many parameter tables on this page; do not start by field at the site. First, clearly confirm the communication link and point table boundaries, then configure them in the order of "channel, device, variable."

What to confirm first?	Information to be received on site.
Communication methods:	TCP client, TCP server, UDP, serial port, OPC UA, OPC DA, MQTT, or plugin self-managed connections.
Connection Parameters	IP, port, serial number, baud rate, check bit, stop bit, account password, certificate, firewall policy.
Device Identity	PLC model, station number, slave station address, rack slot number, DTU number, OPC node space, or MQTT Topic.
Point Table	Variable name, address, data type, unit, range, read/write permissions, alarm threshold.
Verification Method	Use PLC software, instrument surface board, host computer page, or on-site calibration values to confirm the reading results.
Security Boundaries	Which points are read-only, which points are allowed to write, and who needs to confirm before writing.

On-site Recommended Order

When connecting devices on-site, it is recommended to configure them using a "small number of validations, then batch expansion" approach. Do not import the full site table from the start, as communication parameters, station numbers, addresses, and data type issues will be mixed together, making troubleshooting costly.

Sequence	Operation	Create a new channel through standard
1	and fill in IP, port, or serial port parameters.	Channels can connect, and channel logs do not have persistent timeouts or connection failures.
2	Create a new device, select the collection plugin, and fill in plugin properties such as station number, timeout, and byte order.	The device shows online, and there are no persistent read/write errors in the device logs.
3	first establish 3 to 5 typical variables.	The current value matches the PLC software, instrument display, or on-site calibration value.
4	Confirm data type, unit, range, read/write permissions, and alarm threshold.	The checklist matches the final on-site confirmation version.
5	Then batch import or copy the complete point table.	No failed lines in import results, and key points are spot-checked.
6	Export Collection Configuration and Archive.	The delivery package includes the final Excel configuration and point table.

Configuration Levels

Levels	Describes
channels	communication links, such as TCP clients, TCP servers, UDP, serial ports, etc. First, connect the passageways, then continue building the equipment.
Device	Collection Object, select the specific collection plugin. Most equipment needs to be assigned to the channel; Plugins that only support Other can skip the regular channel.
Variable	Points under the device, defining address, data type, read/write permissions, alarms, value filtering, and expressions. First, create a small number of variables for validation, then import the complete point table.

Page Structure

Area	Description
Left Resource Panel	Display devices grouped by channel; channel titles display the number of online devices and channel summaries; Other type devices not bound to the regular channel are displayed in tiled groups. The panel supports filtering by device name, channel name, device status, and plugin name.
Device Context Bar	Shows the selected device, channel, collection plugin, online state, and variable count, with actions for details, editing, and More Functions.
Persistent Variable Workspace	Displays variables for the selected resource. Opening details, logs, or debugging does not replace the variable list.
Operations Workspace	Opens from More Functions and contains Debug, Channel Log, and Device Log tabs. On desktop it can be placed below or to the right and resized by dragging the separator.
Page Operations	The resource panel provides refresh and channel/device management. The variable toolbar Show More menu contains import, export, and test-data commands.

After selecting a channel or device on the left, the variable list on the right is filtered to that scope. Device rows show online status, redundancy role, and collection plugin so you can quickly confirm that each device uses the intended channel and plugin.

Channel Configuration

Click "New" or "Edit" to open the Channel Configuration popup.

Configuration Items	Description
Channel Name	Channel display name; it is recommended to name according to protocol, field link, or device group. Do not use Memory for names; this name is reserved for memory variables.
Description	Purpose of the channel, connection object, or site location description.
Channel Type	Select the communication method. The network channel displays the remote address, binding address, and SSL configuration; The serial port channel displays the serial port parameters.
Enable	to control whether the channel is running. Once closed, devices under this channel cannot collect data through this channel.
Remote Address	The counter address for client-mode connection, commonly in formats such as IP: port or domain name: port, for example, 192.168.1.10:502. TCP clients must provide a remote address; UDP sessions must fill in at least one of the remote address or the bound address. When providing an address with the agreement on-site, you may fill in the prefix tcp://, ssl://, or http(s):// as required by the other party.
Backup Remote Address	Backup peer address for TCP client channels. If the primary remote address fails to connect, the connection is disconnected, or communication times out, the channel will attempt to switch to that address within the same device and channel. As long as either primary or backup links are available, the device will not immediately switch between primary and backup devices due to a single TCP link failure. Leaving a blank means TCP client network redundancy is not enabled; The backup address should not be the same as the remote address.
Binding address	The address where the server mode listens locally on the gateway is commonly used. 0.0.0.0: port means other hosts are allowed to connect,127.0.0.1: port only allows local connections to be allowed. The TCP server must fill in the binding address; UDP sessions must fill in at least one of the remote address or the bound address. If protocol monitoring is required, you can fill in the tcp://0.0.0.0: Port or ssl://0.0.0.0: Port as agreed on site.
TLS switch using SSL	network channels. Enable when the peer requires encrypted communication, bidirectional certificates, or certificate verification; The plaintext protocol on the regular intranet remains closed. When enabling SSL on the TCP server, you must select the server certificate; otherwise, the client cannot complete the TLS handshake.
SSL target host	used by TCP clients to enable SSL for validation certificate hostnames. When connecting via IP but the certificate is issued to a domain name, fill in the domain name in the certificate.
SSL client certificate / server certificate / CA certificate	client certificate used by the gateway to prove identity to the peer; Server certificates are provided to clients when the gateway acts as a server listener; CA certificates are used to verify peer certificates. Certificates must first be maintained in the "Certificate Management" section.
Allows untrusted certificates	Can be temporarily enabled when debugging self-signed certificates. It is recommended to close the production environment and configure the correct CA certificate.
SSL protocol / check certificate revocation	specify TLS version and enable revocation check when handshake failure or on-site security policy requirements; Default is maintained without explicit requirements.
Port Name	The serial port name used by the serial port channel, such as COM1 or /dev/ttyS0. The serial port channel must be filled with the port name, and the host must recognize the serial port.
Baud rate, data bits, check bits, stop bits,	serial communication parameters must be consistent with the field equipment.
DTR / RTS / handshake mode	serial hardware flow control parameters. Adjust when the on-site serial server, RS485 converter, or instrument manual require activation.
StreamAsync	Serial port asynchronous read/write method. On-site can be understood as a serial port-driven read/write mode; When serial communication is stable, it remains at default; when issues such as blockage or untimely reads occur, adjustments can be made according to the requirements of the field driver.
Serial port read/write buffer	The size of the read and write buffers used for serial communication. Scenarios for large numbers of continuous or long messages can be appropriately increased.
Connection timeout	The maximum time a TCP connection is established or waiting for peer response. If the network is slow, the speed can be increased; If the setting is too large, offline detection will slow down.
Cache timeout	The validity period of the data read cache, in milliseconds. If the same address is read repeatedly during the validity period, the cache value will be returned first; It is desired to set 0 each time the device is accessed, and to reduce the repeated read pressure, it can be increased appropriately.
Maximum concurrency	The number of requests allowed to be processed simultaneously on the same channel. When the on-site device request order is strict, keep 1; increase after confirming that the peer supports concurrency.
Heartbeat Content / Heartbeat Time	Used when TCP clients maintain a connection. Fill in when the counterpart requires a fixed heartbeat message; After enabling "Is the heartbeat Hex", use hexadecimal byte parsing.
Maximum Number of Connections / Client Cleanup Time	TCP server channel is used to limit the number of clients and clear idle connections. If there are many upper-level computers or DTU, confirm that the maximum number of connections is sufficient.
DtuId/DtuId: Whether the Hex / Dtu service type	DTU or the passthrough terminal number is used to identify which remote device is connecting. The DTU reports text numbers directly when they are reported; Reporting is that when hexadecimal bytes are enabled, Hex is enabled.

After configuring a backup remote address on the TCP client, the gateway will still prioritize connecting to the "remote address" when the gateway starts or the channel restarts. After switching to an alternate address during operation, it will retain the currently available link; Only try another link if the current link fails again. This configuration only applies to the TCP client channel on the acquisition side and does not affect the TCP server, UDP, serial port, or device primary and backup redundant configuration.

When batch editing channels, only the fields that have actually been adjusted in the batch popup will be modified. Used for unified start-stop, log levels, timeout, heartbeat, SSL, and other public configurations; The addresses, serial port names, and certificates of different types of channels should still be checked individually.

Device Management

Click "Device Management" to open the Device Management drawer.

Operation	Instructions
Search	Search by device name.
Status Filtering	Filter by online or offline status.
Plugin Filtering	Filter by Collection Plugin.
Enable Status Filtering	Enable or Disable Filtering.
Added	to open the device configuration popup and create a device.
Edit	Modify device base information, plugin properties, and redundancy configuration.
Delete	Delete the device. Before deletion, confirm that variables under the device are no longer needed.
Batch Edit	Batch adjust some configurations of selected devices.
Batch Delete	Delete multiple selected devices.
Refresh	Reload the device list.

Device Configuration

Click "New" or "Edit" to open the device configuration popup.

Configuration Items	Description
Equipment Name	The device display name should match the on-site equipment number. Names should not include English periods ., do not use Memory. Memory is the device name used by the system memory variable.
Device Plugin	Select the Collection Plugin. After selection, the device attributes of the plugin will be displayed.
Channel	Select the channel used by the device. TCP, UDP, and serial plugins normally require a channel; use one channel per device unless the plugin manual explicitly documents channel sharing. Plugins that only support Other (without a standard communication channel) can be left blank. You can add, edit, or delete channels next to this field.
Execution interval	The device collects execution intervals, which can be filled in milliseconds or Cron timer expressions, for example, 1000 means 1 second, */5 * * * * * means every 5 seconds. Priority is given to filling in milliseconds during routine on-site cycles; The smaller the spacing, the higher the real-time performance, but it increases the load on devices and gateways.
Enable	to control whether the device participates in collection.
Log Level	Control the detail of equipment operation logs. When troubleshooting, you can temporarily upgrade the log level.
Description	Equipment usage, site number, or installation location.
Notes 1 to 5	Custom extension fields for the project.
Enable redundancy	Configure backup devices for critical equipment.
Redundant devices	After redundancy is enabled, select backup devices. Backup devices should use the same collection plugin and have configured channels, plugin properties, and variables; Equipment that has already been used as a backup for other devices cannot be reselected.
Redundancy Mode	can switch offline, or switch via scripts. Offline switching is suitable for automatic switching when the main device is inaccessible; Script switching is suitable for judgment based on quality, business status, or external conditions.
Scan interval	Redundancy state check interval, unit milliseconds, minimum 10,000. The shorter the interval, the faster the switching, but this increases the frequency of inspections.
Switching Scripts	Redundancy mode is selected when switching scripts. The script should return the decision on whether to switch, making it suitable to decide between principal and standby based on business conditions. When switching scripts, you must select the script.
Plugin Properties	Provided by the selected collection plugin, such as station ID, timeout, byte order, authentication, and subscription parameters. Use the matching topic in the Plugin Manual Index for dynamic properties, address formats, special methods, and verification; configure common variable fields on this page.

Device plugins provide available channel types. When adding or editing a device, select the plugin first and then choose a matching channel. Do not reuse another device's channel unless the plugin manual explicitly says that sharing is supported. If the plugin only supports Other (no standard communication channel), the device can be saved without a channel and appears in the ungrouped area.

Redundant devices should not duplicate overlapping configurations: Do not enable redundancy for backup devices. Before going live, you can disable the main device or disconnect the main link and observe whether it switches to the backup device as expected.

Variable List

The variable list remains visible in the main Collection Configuration workspace and shows the current resource scope.

Tools	Description
Search by variable name	Search by variable name.
Search address	Search by register address or protocol address.
Resource Range Filtering	Select variable ranges through left-side channels or devices.
Status Screening	Filtering by normal or abnormal status.
Refresh	Manually refresh the variable list.
Auto-Refresh	After activating, set the variable values automatically according to the page settings.
Add a variable	Open the variable configuration popup.
Batch Edit	Batch modify selected variables.
Batch Delete	Delete selected variables.
Column Settings	Customize Variable Table Display Columns.

Common columns include device name, variable name, description, register address, current value, original value, last set value, data type, unit, collection group, business group, online status, enabled status, acquisition time, change time, and error information.

Memory variables are maintained on the "Memory Calculation" page. This page only displays variables under the Memory device, suitable for saving scripts, rules, or internal calculation results; The collection configuration page mainly maintains the channels, devices, and variables connected to field equipment.

Variable Configuration

Click "New" or "Edit" in the variable list to open the variable configuration popup.

Configuration Items	Description
Variable Name	Point Name, It is recommended to keep consistent with the device point list.
Belonging Equipment	Variable belonging device. After selecting a device, the address prompt and optional data types will be refreshed by the plugin.
Units	Variable displays units.
Enable	to control whether variables participate in collection.
Description	Description of the purpose of the location.
Variable address	Internal device register, node, Topic field, or protocol address. The address format is determined by plugins; for example, Modbus uses register addresses, OPC UA uses node identifiers, and MQTT uses Topic and Payload fields.
Data Type	Data Type of the Collected Value. It must be consistent with the actual data of the equipment; If the value display is inverted, accuracy is abnormal, or the boolean state is incorrect, the data type, variable address, array length, and plugin byte order should be checked simultaneously. Memory variables are saved by object value, without filling in the field equipment address.
Read and write permissions	Choose read-only, read-write, or write-only. Before writing, confirm that on-site equipment is authorized to distribute the data.
Array length	Length of array-type variables or batch read scenes. Ordinary point variables remain 0 or default; When reading a continuous array, fill in the actual number of elements. Memory variables do not require the array length.
Special Methods	Special read/write methods provided by plugins. After selection, variable addresses are usually used as parameters for this method, and are no longer packaged as regular register addresses; Only select when field protocols, plugin instructions, or debugging requirements are clearly needed.
Execution interval	Variable collection interval. Leave it blank or keep the default as per device interval; When independent cycles are needed, you can enter milliseconds or Cron timer expressions, such as 500 or */10 * * * * *.
Save Initial Value / Initial Value	After enabling saving the initial value, the variable will use the configured initial value when it starts. Suitable for memory variables, state holds, or initial states of script calculations.
Trigger Mode	Memory variables can be configured to trigger by variation, interval, or interval/change. Calculate the linkage according to the appropriate variation; Calculated by interval suitable cycle; The intervals/variations suit scenarios where both are needed. Ordinary collection variables perform periodic collection by device or variable, and do not require maintenance.
Read expressions / Write expressions	Read expressions to convert the collected raw values into business values; Write expressions are used to convert the value written to a page or external into the value required by the device. Ordinary collection variables select data conversion scripts; Read expressions for memory variables are used to calculate memory values. After selecting an expression with parameters, you need to fill in the expression parameters.
Read expression parameters / Write expression parameters	Input parameters required by the expression. The page displays parameter names and data types; Variables cannot be saved when required parameters are missing.
Collection Group	Set business group names for variables. Plugins that support packaged collection try to merge and read variables within the same group as much as possible; Data forwarding can also be filtered by collection group or in batches.
RPC writes	to control whether this variable allows external systems to write points backward via RPC, MQTT, OPC UA, Modbus slave stations, etc. Variables involving device control should be turned on cautiously.
Write Check	After a successful write, read the same variable again and compare the readback value with the write value. Suitable for points where confirmation of write is indeed effective; Devices that only write variables, have delayed effects after writing, or have proportional conversion or writeback rounding points should not be enabled arbitrarily.
Notes 1 to 5	Custom extension fields for the project.

When batch editing variables, only the fields that have been modified in the batch popup are saved. Before batch modifying data types, addresses, read/write permissions, expressions, or alarms, you should first filter variables of the same device, protocol, or data type to avoid applying incompatible configurations to other locations.

Alarm Configuration

Configuration Items	Description
Boolean Alarm / Boolean Off-Alert	Boolean variable can be configured to enable and disable status alarms separately. Alarm activation is used when the value is true, and off alarm is used when the value is false.
High, high, low, low-low alarms	Numerical variables can be configured with upper and lower limit alarms. When enabling multiple limits, the threshold should meet "High High > High > Low > Low Low"; otherwise, an error will appear when saved.
Custom alarms	Alerts configured with custom conditions. Suitable for alarms such as equipment status codes, quality codes, and combination conditions, where only upper and lower limits can be described.
Alarm code / alarm text	Alarm code is used to distinguish alarm types; the alarm text is the explanation seen by the duty personnel. It is recommended to clearly state the target, conditions, and direction of handling.
Alarm Level	Alarm severity, ranging from 0 to 10, with higher values indicating more severity.
Alarm Delay	Triggered only after the alarm condition has been continuously reached for a set time, in milliseconds. Used to filter transient shaking; Setting it to 0 means the alarm will sound immediately once the condition is met.
Suppression Expression	Suppression of corresponding alarms when conditions are met, suitable for maintenance, interlocking, or scenarios where alarms are temporarily omitted under specific working conditions. The suppression expression only affects alarm triggers and does not change the variable acquisition value.

Value Filtering

Configuration Items	Description
Range Filtering	Filtering outliers by minimum and maximum values. Suitable for scenarios such as occasional sensor out-of-bounds and extreme wire disconnections. After activation, you must fill in the minimum and maximum values, and ensure the maximum value is not less than the minimum.
Amplitude Filtering	Filter mutation values based on maximum amplitude or percentage change. Suitable for analog quantities such as temperature, pressure, and flow rate that should not fluctuate dramatically instantly. The maximum percentage change is filled in from 0 to 100.
Continuous Filtering	Handles duplicates or abnormal consecutive values based on the number of consecutive anomalies. Suitable for scenarios where you need to wait for the anomaly to persist multiple times before accepting or discarding it. Start from 1 in the maximum number of consecutive attempts.

Value filtering is only used for numeric variables; Strings and boolean variables do not display this tab. If the filtering parameters are set too tightly, true changes will be filtered out. Before setting, confirm based on the field range, sampling cycle, and allowable fluctuation range.

Variable Details and Writing

Click "Details" in the variable row to open the variable details drawer.

Partition	Description

Expression Configuration	Displays read/write expressions and parameters.
Alarm Information	Variable Alarm Display the alarm configuration and runtime alarm status after alarm activation is enabled.
Value filtering	variable is configured to display filtering parameters during value filtering.
Historical Data / Historical Alarms	Query the history of the current variable in the Details drawer; Historical alarms are displayed when variable alarms are enabled.

Click "Write" in the variable row to open the write popup.

Configuration Item	Description
Device Name	The device to which the current variable belongs, displayed read-only.
Variable Name	Current Write Variable, read-only display.
Current value	Write the variable value read from the previous page.
Write Value	The value to be sent, formatted to match the variable data type.

Note:

Writing variables will affect on-site equipment. Before performing writes, please confirm the variable read/write permissions, write value ranges, and on-site security conditions.

Device Details and Debugging

Select a device on the left. Use the information icon in the device context bar to open the details drawer. Click More Functions to display the operations workspace; it opens on Debug by default.

Entry or Tab	Description
Device Details	View basic device information, channel configuration, runtime state, plugin properties, and redundancy configuration.
Debug	Open plugin tools such as address read/write, node browsing, message capture, or protocol-specific diagnostics.
Channel Logs	View the communication logs of the channel to which the device belongs.
Device Logs	View the current device operation logs and error messages.
Workspace Layout	Select Bottom or Right. Drag the horizontal separator to change height, or the vertical separator to change width.

The image above only locates the common Debug entry. It is not a plugin-specific debug screen; the available tabs and operations depend on the selected plugin and are described in its manual.

When sufficient horizontal space is available, use the layout button and select Right to keep variables and diagnostics side by side.

Channel and device logs retain filtering, automatic refresh, export, and pagination inside the workspace.

When a plugin provides a protocol panel, select Protocol Debug and then use the tabs on that protocol page. The following example shows an IEC104 master.

Switching devices immediately closes the previous debug panel and message-capture connection. Start message capture again from the new device when required.

For detailed debugging steps, open the matching page in the Plugin Manual Index.

Test Data

Click "Show more → test data" to open the test data generation popup. This feature is used to generate demo or stress test configurations.

Configuration Items	Description
Data Type	Select Normal Test Data or DTU Test Data.
Number of variables	Number of variables generated under standard test data.
Number of devices	Number of test devices to be generated.
Slave Address	Slave address or connection information used when generating the device.
Enable data forwarding	Configure whether data forwarding is generated synchronously under normal test data.
Generate	Generate test configurations based on the quantity and options entered in the pop-up.

Normal test data creates a separate collection channel for each test device, which is useful for checking multiple devices and connections. DTU test data uses one TCP service channel for multiple DTUs; that is a DTU-specific shared-connection mode, not the default for ordinary collection devices.

Before using test data in production environments, it should be confirmed that the name and quantity are not confused with the official configuration.

Import and Export

Collect Configuration Import and Export is located in the "Show More" menu at the top right of the variable list.

Operation	Description
Import Collection Configuration	Import channel, device, and variable configuration.
Export the current collection configuration	Export by page filter criteria and resource range.
Export all collection configurations	Export all collection configurations.

After importing is complete, the import result will be displayed. When importing on site, focus on checking the failed rows, field names, and error details, then correct the Excel prompts and re-import.
