EPM Programmable Settings Blocks

The EPM Modbus Register Map can be found in Chapter 2. This chapter gives a detailed description of each of the Programmable Settings Blocks.

7.1: Communication Settings Block (45057-45074)

•Device Address - 2 bytes, unsigned integer, ranging from 0000H to FFFFH

•Protocol - 1 byte, unsigned integer.

•Baud Rate - 1 byte, unsigned integer.

•Parity - 1 byte, unsigned integer.

•Stop Bits - 1 byte, unsigned integer.

•Data Bits - 1 byte, unsigned integer.

•Response Delay - 1 byte, unsigned integer.

•Port Mode - 1 byte, unsigned integer. The value 1 means Master; value 0 means Slave. Port 1 is always a Slave.

7.2: Limit Settings Block (45077-45204)

Limit Comparisons - Internal Representations

An EPM device has 32 Limits Objects.

Each Limit Object performs two independent comparisons with a selected computed value and combines them into a combined output. Information needed to perform these actions: channel identification, comparison values, comparison directions and combination type.
