Step 2. Map Points to Modbus Data Addresses

About this task

Map (link) CIMPLICITY points to Modbus data addresses by creating register-mapping Register Mapping Records definitions within the configuration file.

todo: To maximize throughput:

Procedure

  1. Map:
    • Boolean points to coil (0X) or input status (1X) data addresses.
    • Analog points to input register (3X) or holding register (4X) data addresses.

    Avoid gaps in allocated data addresses.

  2. Edit the configuration file to specify the
    • Communications port parameters,
    • Trace log parameters, and
    • Modbus register limits.
