Measured value averaging type:

0 – No averaging

1 – Moving averaging (Number of values for moving average: 2, 4, 8, 16, 32, 64 and 128)

2 – Recursive averaging (Number of values for recursive average: 2…32768)

3 – Median (Number of values for median: 3, 5, 7 and 9)

Statistic depth: 0, 2, 4, 8, 16…16384; 0 = infinite

Appendix| EtherCAT

Error handling:

0 – Output of error value

1 – Hold last valid value for a number of measurement values (Number of held values: 0….1024,

0 = infinite)

Use spike correction

0 - without spike correction

1 - with spike correction

Spike correction evaluation length: Number of evaluated values (1 ... 10)

Spike correction range: Max. tolerance range in mm (0.0000000 ... 100.0000000)

Spike correction count: Number of corrected values (1 ... 100)

Reset counter:

- Bit 0: Reset time stamp counter

- Bit 1: Reset measured value counter

- Bit 2: Reset trigger counter

Resetting the individual counter is done by setting the corresponding bit to 1.
