Interference frequency suppressionNone | 10 Hz | 50 Hz | 60 Hz | 400 Hz
efresh rate / conversion rateNumber of active channels x conversion time +16 ms for wire break detection for each channel when activated.
The conversion time will depend on the interference frequency suppression:
None: 8 ms
400 Hz: 45 ms
60 Hz: 109 ms
50 Hz: 128 ms
10 Hz: 342 ms
DiagnosesUpper measuring range limit exceeded (overflow), lower measuring range limit fallen below (underflow), wire break (for 1 ... 5 V only), parameter assignment error
Process alarms Upper and lower limit per channel
Error limits
