Example 5
Signal delay from the input (group 1) with a Bessel filter with 1 kHz to the field-
bus master (group 4).
• A/D converter (ADC) plus filter: 690 μs.
Added to this is a jitter of up to 52 μs, as the A/D converter is not synchro-
nized with group 1. Group 1: 690 μs + 52 μs max.
• Fieldbus output with EtherCAT or PROFINET (4 kHz frame rate): max.
370 μs + 250 μs + 250 μs (typ. 250 μs + 125 μs + 250 μs = 625 μs).
So the total phase delay is between 1.315 ms (min.) and 1.612 ms (max.).
