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.
Q
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.
