Yokogawa  ALE111-S50  Model ALE111 Ethernet Communication Module

This document describes about Model ALE111 Ethernet Communication Module 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 Ethernet communication module. This Ethernet communication module can be mounted on SSC60□ and SSC50□ safety control units and SNB10D safety node unit that are connected with safety control units by ESB bus
