RS485 to Modbus TCP adapters

Some devices communicate over Modbus RTU (RS485) rather than Ethernet. To make these devices reachable by the controller over the network, an RS485-to-Modbus-TCP adapter (gateway) converts the serial RS485 signal to Modbus TCP.

Use one of the supported adapters below when a device only offers an RS485 interface.

After the adapter is configured, the device can be added on the platform like any other Modbus TCP device. See Adding and verifying devices.
