Networks and sofware

Modbus

Modbus is the most widely used communication protocol in industrial networks.

It operates in master-slave mode. The devices (slaves) communicate one after the

other with a gateway (master).

Masterpact, Compact NSX, PowerLogic and Sepam products all operate with this

protocol. AModbus network is generally implemented on an LV or MV switchboard

scale. Depending on the data monitored and the desired refresh rate, a Modbus

network connected to a gateway can serve 4 to 16 devices. For larger installations, a

number of Modbus networks can be connected to an Ethernet network (TCP/IP/

Modbus protocol) via their gateways (EGX).
