Reintegration After Discrepancy Error Parameter
This parameter is used to specify when a discrepancy error is regarded as eliminated and,
thus, when the relevant input channels can be reintegrated. The following can be assigned:
● "Test of 0-signal required" or
● "Test of 0-signal not required"
Requirements
You have assigned the following:
● Evaluation of the sensors: "1oo2 evaluation"
"Test of 0-signal required"
If you assigned "Test of 0-signal required", a discrepancy error is regarded as eliminated
once a 0-signal is present again at both of the relevant input channels.
If you are using nonequivalent sensors, i.e., the "Type of sensor interconnection" is set to "2-
channel nonequivalent", a 0-signal must be present again at the channel supplying the
wanted signal.
For information about which F-module channels supply the wanted signals, refer to the
manual for the F-module you are using.
"Test of 0-signal not required"
If you assigned "Test of 0-signal not required", a discrepancy error is regarded as eliminated
once the discrepancy at the two relevant input channels disappears.
F-modules in SIMATIC S7 for which the "Reintegration after discrepancy error" parameter is
not available also exhibit this behavior.
