Modbus server (slave) devices include: ModbusSlaveDeviceand ModbusTcpSlaveDevice. Both represent the station as a virtual Modbus slave, that is, the station listens for Modbus queries from a remote Modbus master, and sends responses.
Both Modbus server devices are similar, having a single frozen Points device extension, with the default Modbus Server Point Manager view. The same type of Modbus server proxy points are used under Points device extensions.
In addition to common device slots, both types of Modbus server devices have similar properties for Modbus configuration. This includes overrides of network level device data settings and register range configurations for Modbus data items.
