I have this build. Counters work fine with a speed of less than 5ms.

Parametr antyaliasingu w moim przypadku nie wpływa na prędkość przy 60Hz

Hi,

yes, the cycle time/update time of the complete module is the sum of the conversion time of all used channels.

In addition to that, also the profinet cycle (if used decentral) and also the cpu cycle time effects the update time of the values, as the process image of inputs is generated at the beginning of the OB1 cycle.

Possibilities to improve the time:

1. deactivate unused channels in hw config

2. use an interrupt ob and update the process image / TPA with the interrupt ob

3. use a different "Interference voltage suppression for interference frequency", this prameter directyl effect the conversion time of the channel. But be aware, officially as per manual, this parameter should be set to the frequency of the power supply! If you are using different values, this would improve the update time, but may have negative impact to the quality of measurement!

4. use a high speed (HS) analog input module
