What happens?
The resistance value changes faster than the sampling rate set.
When does the problem occur?
The EPM-S404 I/O module uses the lowest conversion time set at the four inputs for sampling purposes.
Which products are affected?
PLC Designer from V3.1
EPM-S404 (4 analog inputs for resistance measurements of the I/O System 1000)
Possible diagnostics?
None.
Short-term measures/recommendations?
Set the same sampling rate for all channels.
Evaluation:
The EPM-S404 I/O module uses the smalles conversion time set at the four analog inputs for sampling the channels irrespective of the conversion time set.
