Page 72: Modbus Information
ET-2200 Series Ethernet I/O Modules 6. Modbus Information The ET-2200 series is a family of IP-based Modbus I/O devices that allow you to remotely control DI/DO terminals via an Ethernet connection and uses a master-slave communication technique in which only one device (the master) can initiate a transaction (called queries), while other devices (slaves) respond by either supplying the requested data to the master, or by taking the action requested in the query.
Page 73: Modbus Message Structure
ET-2200 Series Ethernet I/O Modules 6.2 Modbus Message Structure Modbus devices communicate using a master-slave (client-server) technique in which only one device (the master/client) can initiate transactions (called queries). The other devices (slaves/servers) respond by either supplying the requested data to the master, or by taking the action requested in the query.
