Mc1E_AsciiMaster

Purpose​

Mitsubishi MC 1E ASCII protocol PLC address read and write driver

Open the plugin​

Enter "Development Configuration → Collection Configuration", create a device and select "Mc1E_AsciiMaster" in "Collection Plugin".

Supported channels and data types​

Channel typePre-configuration check
Serial PortConfirm that the serial port is not occupied by other programs and maintains the same baud rate, data bits, stop bits and parity bits as the device.
TCP ClientConfirm network reachability of the device IP, port, and gateway to the device.
TCP serverConfirm that the local listening address and port are available, and allow on-site devices to actively connect to the gateway.
UDPConfirm the local binding address, port and firewall rules, and check the source of the packet.

Optional data types: Boolean, Byte, Int16, UInt16, Int32, UInt32, Int64, UInt64, Float, Double, String, Decimal

Protocol parameters​

SettingDescription
PLCIDDefault: 255; fill in: text input. Set the PLCID used for protocol communication.

Address rules​

  • MC 1E ASCII bit device: B, CC, CS, F, M, S, TC, TS, X, Y.
  • MC 1E ASCII WORD device: CN, D, R, TN, W.
  • B and W addresses are parsed in hexadecimal; when the digital part of X and Y starts with 0, they are parsed in octal, otherwise they are parsed in hexadecimal; other device addresses are parsed in decimal.
  • WORD can access individual bits using "address.bitoffset" with a bit offset in the range 0 to 15.
  • Example: M100, D100, D100.3, B10, W10, X010, Y10.

Functions​

FunctionPurpose
Read and writeRead a confirmed point and write only to an approved test point.
MessagesView sent and received frames, protocol fields, and error details.

Device debug​

Enter "Development Configuration → Collection Configuration", select the current device and click "More Functions", then open "Debug".

Dedicated debugging page​

Open Development Configuration → Collection Configuration, select the device, and open More Functions → Debug. The following image shows the plugin-specific debug page.

Verify the configuration​

Use a confirmed on-site address to perform reading. The return value, data type and byte order should be consistent with the point list; after the writable point is written, it should be read back according to on-site requirements.

Troubleshooting​

  • Address reading failed: Check the station number, register or node ID one by one according to the address rules on this page, and confirm that the data type is consistent with the device point list.
  • The serial port device does not respond: Confirm that the serial port is not occupied, and check the baud rate, data bits, stop bits and parity bits.
