Internal Design and Communication Processing

This communication module uses two UARTs for simultaneous serial handling. Two line drivers convert logic levels to RS232 or RS485 signals. The ABB 1SAP170902R0001 supports Modbus RTU and Modbus ASCII protocols. You configure each port’s baud rate and protocol via PLC software. The module buffers incoming and outgoing data for the CPU. Consequently, this module enables reliable data exchange on two independent networks.

Installation and Configuration Guide

First, mount this module onto a standard 35 mm DIN rail securely. Next, connect your serial devices to the RS232 and RS485 ports. Use shielded cables for both connections to reduce noise. Then, configure each port’s baud rate and protocol using AC500 software. Use RS232 for short-distance connections up to 15 meters. Use RS485 for long-distance networks up to 1200 meters. The module automatically buffers incoming messages for the CPU. Two LED indicators show transmit and receive activity per port. This communication module works with all AC500 CPU models including 1SAP140200R0160 and 1SAP140300R0160. Always terminate the RS485 line with proper resistors for long cable runs.
