Dear Sir,

We are trying to change in Hardware configuration of one segment and after changing when I calculate Schedule or Click on optimize micro cycle it shows error.

"calculated schedule canceled"
The schedule calculation could not executed

select option "automatic calculation" in bus parameter tab
click calculate schedule on the micro cycle tab

I have checked selection is ok and tried but after saving and compilation it shows error again and again.

My configuration of DCS is as follows...
Wehave PCS7 (V8.0) with S7-417-4H PLC (FF base device)

Hi,

could you solve the problem or is it still exist?
