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.
After this time the signal is available inside the ClipX.
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 ana-
log output, another millisecond is added, i.e. the total phase delay in this case is
1802 μs.
