Getting started
RS485 to Modbus TCP adapters
Use an RS485 to Modbus TCP adapter when a device only offers a serial interface, so the controller can reach it over the network.
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.
