I have a CPU 314C2DP which does not supports OB32. Is there any other way to realise the same. Also I want a button in my HMI by clicking the same I want to synchronise the clock of the Module. Is this possible? regards Shamsher

Only bigger CPU´s (S7-400) have more than one time-cycled OB like the OB32. You only have to adaptthe cycle time from 100ms (standard) to 1000ms. Best regards…

neo Posts: 264 Rating: (59)	Hello Shamsher, You have to open properties of the CPU in the Hardwareconfig. Ther you have to adapt the timefor the ob35. I´m afraid I´ve no step 7 here at the moment, so I can´t tell you the correct name of the index in the properties of the cpu. But I´m sure you will find the parameter if you´ll have a look for interrupt processing OB´s. best regards...
