I'm able to download the datablocks from our PLC, but how do I find the status of an input/output in the datablock?
I mean, we have the datablock in hex. How can we find on what address the parameter is located, and how many bytes it holds. We have analog / digital inputs and outputs.
Note, we don't have physical access to the PLC. The PLC is on the other side of the world. We just have remote access.
So trial and error is not possible.
