I 'm new to iRidium and i am working on my first project.
I have a Beckhoff PLC CX8090 and communication to iRidium over Modbus TCP. I am having trouble adressing my variables in Modbus. Because I have little to no experience with Modbus TCP ....
Below you can see what i have found:
Name MW0 as adress in the PLC (just as reminder)
Push button to activate M0.0
Send number 1 (dec) -> bin 0000 0001 this is M0.0 in PLC
Push button to activate M1.0
Send number 256 (dec) -> bin 0000 0001 0000 0000 this is M1.0 in PLC
I can't find a way how to connect with the I/O's directly to the PLC.
Can anyone give a concrete example to me how I can retrieve / send certain addresses ? The inputs of the PLC i am using is starting from I19.0 , the outputs from Q19.0.
Thanks in advanced
