good afternoon.
i have a sinumerik 880t ga2. i don't have any alarm or warning.
the problem is as follows: in the plc program. there is 1 binary output card (address 4),
which does not activate the binary output.
with step 5 we review the segment status and see that output 0-->1 is activated.
we also check in diagnostics- plc status and observe the change of the bit from 0-->1. but there is no 24vdc output on the card.
exchange the position of 2 cards as well as their addresses. the binary output card that was not working now works with the other direction.
but there is no output on the other card. with address 4.
i reviewed the tea2 and there are no changes in the values.
any suggestions what to review?
i thank you for your help.
