Description

ALR121-S50 YOKOGAWA Serial Communication Modules 4-wire System Multipoint SCS Modbus Communication

Description:

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.

The dual-redundant configuration of the network can be available by establishing an independent transmission path from the Modbus master for every two the serial communication modules mounted in the SCS.

However, control/ stand-by switching function in between the dual-redundant serial communication modules mounted on adjacent slots is not supported.

ALR121-S50 YOKOGAWA Serial Communication Modules 4-wire System Multipoint SCS Modbus Communication​

Communication module’s definition information, Modbus device addresses, mapping definition of SCS data, and so on are to be downloaded using engineering function of a Safety Engineering Station (SENG).

When a data is sent from an external Modbus master (external device), the SCS’s CPU receives it through its serial communication module. The SCS’s CPU sends a response message using the Modbus slave communication function to the Modbus master in response to the data request.

The SCS Maintenance Support Tool displays error information and notifies the error status using the SCS status display function when an error in the serial communication module and communication content occurs.
