  • Page 6: General Information About Modbus

    Master devices control data traffic on the bus. A master is allowed to send messages without an external request. Masters are also called "active devices" in the Modbus protocol. Slave devices such as AUMA Modbus actuators are peripheral devices. Typical Slave device slave devices are input/output devices, valves, actuators, and measuring transducers.
