Our RESI-1RS485-ETH and RESI-1RS232-ETH gateways allow the integration of MODBUS/RTU slave devices or devices using an ASCII or binary protocol into an Ethernet network. Therefore the gateway exchanges data bidirectional between Ethernet and the serial line (RS232 or RS485).
A special mode for internal conversion between MODBUS/TCP and MODBUS/RTU protocol can be enabled in the gateway. This allows controllers with MODBUS/TCP protocol to communicate with MOBUS/RTU devices directly.
Our RESI-1RS485-SIO and RESI-1RS232-SIO devices are used to convert between different protocols. Both modules offers on one side a RS232 and RS485 interface. On the other side the RESI-1RS232-SIO offers a galvanic insulated RS232 interface and the RESI-1RS485-SIO offers a galvanic insulated RS485 interface. Please contact sales@RESI.cc for more details about those products.
Our gateways are intended for connection to any type of controller:
PCs, PLCs, AutoGers, media controls, minicomputers, Raspberry Pi's, Arduino's or special hardware
HOW TO CONFIGURE?
The gateways offer a Web page to define the Ethernet parameters. The serial parameters are set via MODBUS registers with a special setup method. Please consult the manual for more details how to configure this devices.
