Step 2. Map Points to Modbus Data Addresses

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

  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.

  1. Edit the configuration file to specify the:

Communications port parameters,

Trace log parameters, and

Modbus register limits.
