We had some strange behavior in our project that is based on the V2.3 of codesys where we used TON and TOF with PT := 0 ms. We still saw a one cycle-delay in changing output Q when input IN changes. We thought this was strange and tested it with V3 of codesys which we are in the process of migrating to. V3 codesys did not have this extra delay.
Can someone confirm that this behavior is different in V2.3 and V3 of codesys? Can the V2.3 behavior be considered a bug?
I know it does not make much sense to use TON and TOF with PT := 0 ms but for us we use standardized software and then delays can be controlled with inputs and if I set delay to 0 ms delay I want to know that I actually get 0 ms delay.
