Success Story

Application : Medium to Low Voltage substation
Location : Malaysia, RAPID Petronas project
System integrator: Schneider Electric
Requirements : Redundancy and data concentration
Set up time : April 2016
System description:
Manage via Modbus TCP SCADA the substation infrastructure (Modbus RTU based). Each switchboard
is made of 190 slaves that need to be accessed simultaneously for data, diagnostics and configuration.
Data access via Standard Gateway is not possible since a complete data update is needed every 1s. There are 2
Modbus Concentrators per switchboard, that alongside communication will provide diagnostics to the EWS.
Solutions provided:
• Definition of the Ideal Network Topology
• Customs designed redundant Concentrators
• Managed switches with RSTP redundancy
