Allen-Bradley PCCC master
Allen-Bradley PCCC file table address read and write driver
Open the plugin
Enter “Development Configuration → Collection Configuration”, create a device and select “PCCCMaster” in “Collection Plugin”.
Supported channels and data types
| Channel type | Pre-configuration check |
|---|---|
| TCP Client | Confirm network reachability of the device IP, port, and gateway to the device. |
Optional data types: Boolean, Byte, Int16, UInt16, Int32, UInt32, Int64, UInt64, Float, Double, String, Decimal
This list describes types allowed by the plugin editor. Address width, arrays, string length and read/write restrictions still follow this page; it does not mean that every address supports every type.
Plugin properties
Protocol parameters
| Setting | Description |
|---|---|
| Target slot | Default: 0; fill in: text input. Set the slot number where the PLC CPU module is located. |
| Backplane port | Default: 1; fill in: text input. Set up a controller backplane port or path segment. |
Address rules
| File type code (decimal) | File type | Address format | Example |
|---|---|---|---|
| 130 | Output | O{file}:{element} | O1:10 |
| 131 | Input | I{file}:{element} | I2:20 |
| 132 | Status | S{file}:{element} | S3:30 |
| 133 | Bit | B{file}:{element} | B4:40 |
| 134 | Timer | T{file}:{element} | T5:50 |
| 135 | Counter | C{file}:{element} | C6:60 |
| 136 | Control | R{file}:{element} | R7:70 |
| 137 | Integer | N{file}:{element} | N8:80 |
| 138 | Floating point | F{file}:{element} | F9:90 |
| 141 | String | ST{file}:{element} | ST10:100 |
| 142 | ASCII | A{file}:{element} | A11:110 |
| 145 | Long integer | L{file}:{element} | L12:120 |
The file and element must exist in the controller; these examples explain syntax and do not create files. N7:0 is element 0 of integer file 7, rather than a CIP tag name. For bit access, also supply the bit index from the point list.
Device debug
Enter “Development Configuration → Collection Configuration”, select the current device then open “Protocol Debug” at the top of the workspace.
Read and write
Perform read or write verification according to the current plugin address rules; confirm on-site security and permissions before writing.
Messages
Check the device’s message sending and receiving and protocol logs to locate message format, connection and parsing problems.
Functions
| Function | Purpose |
|---|---|
| Read and write | Read a confirmed point and write only to an approved test point. |
| Messages | View sent and received frames, protocol fields, and error details. |
Verify the configuration
Monitor N7:0 online in the PLC engineering tool, compare its value with the gateway variable and confirm advancing sample times.
Troubleshooting
- File-table syntax is area+file:element rather than a CIP tag name; check file type, element width and target route.
