Codesys can definately be a Master for both Modbus RTU and Modbus TCP/IP. I'm not sure about Modbus RTU over TCP though. If you have the time and the physical hardware see if it's just Modbus TCP/IP.
Do you have a part number or manual for the weighing module?

Hello,
I would like to ask for your help.
I will have a weighing module which supports Ethernet, RS232, RS485 interfaces.
I would like to use MODBUS communication protocol which the device supports as follows.
• RS484 - RTU (device interface RS485, frame RTU),
• TCP/IP - RTU (device interface Ethernet, frame RTU),
• TCP/IP - Open ModBus (device interface Ethernet, frame Open Modbus).
So my question is whether I am able to communicate with this device using CODESYS runtime (acts as a Modbus master).
I really appreciate your help.
Thanks in advance.
Best Regards!

I have raised the question to the supplier as well.
Thanks for your help.
