I am new on CODESYS env.
I would like to do some Modbus TCP, but I am wondering If using codesys you must use the device "Modbus_TCP_Client" & "Modbus_TCP_Server".
I would like to do it without device, only using ST. Is that possible ?
I try the example : MODBUS_master_example, but it is not working.
If it is possible to dot it without any Device I will show my code.
Thx a lot

The Modbus Master example must work. We have used this several times on multiple projects.
