Step 1. Edit the Modbus RTU Slave Configuration File

When a new CIMPLICITY project is created, a template configuration file is created for the Modbus RTU Slave Interface. The file has a comma-separated value (CSV) format similar to the format used by the CIMPLICITY import/export utility.

Modify the configuration file to specify the:

  • Communications port parameters.
  • Trace log parameters.
  • Modbus register limits
  • Point / register mappings.

Information about:

  • The file naming convention.
  • Types of Modbus RTU Slave configuration records.
