Conversion Time
The analog signals are converted one by one down every channel. Disabling one or several channels will
shorten the entire A/D conversion cycle.
'Filter' in this case means to compute an average when the set filter time is over.
Analog value conversion runs cyclically and is not synchronized with the receipt of EtherCAT telegrams.
The cycle consists of the analog value conversion plus transmitting the values into the EtherCAT data area.
