Modbus Register Limits Record

The configuration file may contain a Modbus Register Limits record. These limits are applied only to CIMPLICITY points mapped to analog registers (register type 3X or 4X).

The format for the Modbus Register Limits record is:

RL,<low limit>,<high limit>

Where

RL

Identifies the record as a Modbus register limits record.

<low limit>

The minimum value accepted from a CIMPLICITY point.

Valid range of values: 0 to 65535.

Must be less than <high limit>.

Default value: 0.

<high limit>

The maximum value accepted from a CIMPLICITY point.

Valid range of values: 0 to 65535. Must be greater than <low limit>.

Default value: 65535.

Note: If the Modbus Register Limits record is not defined the low and high limits are 0 and 65535, respectively.
