I'm configuring a profinet network in TIA portal v13, comprising the following components:
Knowing that there would be i/o expansion in the future, I manually set the CU240 addresses (setpoint & actual) at I111/Q111, I121/Q121, I131/Q131. I did this by selecting each drive in network view and entering the two addresses via the cyclic data exchange tab.
Before I had completed the design, the first extra addresses came along. These went in ok until I'd added a couple of input modules then the auto-increment jumped from I19 to I86. I re-checked the drive addresses but I figure that there must be others in the CU240 config; indeed, there must be loads but I can't see them. If I try to manually re-address the digital input at I86 to anything lower, it gives an "already used" error.
So, the question is (I think) where do I access the apparently hidden CU240 addresses to allow me to shunt them out of the way of the remote i/o? Or do I have to delete the drives, add the i/o and re-allocate the drives after?
Thanks.
