Hello, You won't be able to use the node-red-contrib-s7 nodes without an ethernet port on the PLC. Unfortunately the IOT2020 does not have the serial interfaces that the IOT2040 does. So you would be left with either the USB interface or Arduino pins to communicate Modbus RTU. One user in this forum mentioned that it works with a USB converter, but we have no example or hardware suggestion for this. Kind regards! |
