Schneider LUFP7 Communication Gateway

Feature & Principle

It is a dedicated fieldbus gateway of Schneider TeSys series. It acts as PROFIBUS DP slave on the upper network and Modbus RTU master on the lower network. It cyclically reads and writes register data of Modbus devices and forwards data to PROFIBUS DP master PLC. It is configured by ABC-LUFP software, realizes protocol conversion for motor starters, soft starters and inverters, solves the communication interconnection problem between different bus systems.
