Reintegration After Discrepancy Error; Parameters Of The Channels; Channel Activated - Siemens Simatic S7-1500 Manual

4.2 Explanation of parameters
Behavior after expiration of the discrepancy time
If no agreement (when checking for non equivalence: inequality) of the input signals exists
once the assigned discrepancy time expires, for example, due to a break in a sensor wire, a
discrepancy error is detected and the "Discrepancy error" diagnostic message containing
information on which channels are faulty is generated.
4.2.3.4

Reintegration after discrepancy error

Function
This parameter specifies the criteria for when a discrepancy error is regarded as corrected,
thus enabling reintegration of the relevant input channels. The following parameter
assignment options are available:
● "Test 0-Signal necessary"
● "Test 0-Signal not necessary"
Requirements
You have assigned the following:
● "Sensor evaluation": "1oo2 evaluation, equivalent" or "1oo2 evaluation, non-equivalent"
"Test 0-Signal necessary"
If you have assigned "Test 0-signal necessary", a discrepancy error is not regarded as
corrected until a 0-signal is present at both of the relevant input channels.
If you are using non equivalent sensors, which means you have set "Sensor evaluation" to
"1oo2 evaluation, non-equivalent", the result of the channel pair must provide a 0-Signal
again.
"Test 0-Signal not necessary"
If you have assigned "Test 0-Signal not necessary", a discrepancy error is regarded as
corrected when a discrepancy no longer exists at both of the relevant input channels.
