We have to migrate a project from S7 300 to S7 1500 where FB41 CONT_C is used.
It is called in OB (every cycle), I see that the parameter 'Cycle' is 500 ms.
I don't know what the average OB1 cycle time is.
I know this was not implemented as it should.
But I should want when implemented in S7 1500 that the pid parameters don't have to be retuned.
Does the calling frequency has an influence on the effect of the proportional parameter?
What about the I-parameter?
In the original program, if the OB1 cycle time would fi be 40ms, the 'Cycle' parameter of FB41 is at 500 ms, what will be the influence? If I would like to implement it in a cyclic OB, what cycle time should I choose?
