that places the value on the ClipX bus in order to get the time from the sensor until a
response occurs: 1.69 ms min. and 2.742 ms max. with 1 kHz Bessel filter. So the total
phase delay is 1.94 ... 3.992 ms.

Example 4
Signal delay from fieldbus master (PLC) to ClipX. From there it can be further processed
or outputted as an analog signal.
•
Fieldbus output for EtherCAT or PROFINET (4 kHz frame rate): 250 μs + 250 μs +
250 μs = 750 μs.
The signal is available in the ClipX after this time.
•
If you want to output the signal via the analog output of this ClipX, 52 μs is added
(group 1), i.e. the total phase delay is then 802 μs.
•
If you want to calculate the signal via an internal calculation channel before analog
output, another millisecond is added, i.e. the total phase delay in this case is
1802 μs.
