Description

YOKOGAWA RS422/RS485 Module ALR121-S00

Models ALR111 and ALR121 Serial Communication Modules used with a safety control station (SCS) for performing Modbus communication.

By using the SCS’s Modbus slave communication function, the data in SCS can be set or referred to by the Modbus master which is as separate system from SCS via a serial communication module. Furthermore, the subsystem

data such as from sequencers can be set or referred to via a serial communication module using SCS’s subsystem communication function.

These serial communication modules can be mounted on a safety control unit and a safety node unit.

Hardware specifications of ALR111 and ALR121 serial communication modules are as shown below. These modules are interference-free modules that have no interference with the safety loop.

*1: A unit of SCS is capable of handling multiple communication functions: however, different types of communication functions cannot be simultaneously performed on a serial communication module. It means that two ports must have identical

communication functions.
