■Application and example of double input discrepancy detection (with discrepancy detection
time not specified)
When a certain double input discrepancy detection time cannot be applied for the application, this function is used. Even if a
double input discrepancy is detected, a double input discrepancy detection error does not occur immediately. The error occurs
only when certain conditions are satisfied.
The following shows an example of when this function is used for the double
sensor of door switches that are opened or closed manually.
If a door is half-opened, fully open it once and then close it. With this operation
you can confirm that both of door sensors turn off and distinguish the
discrepancy due to failure from the discrepancy due to a half-closed door. In
addition, the door can be used continuously without a double input discrepancy
detection error.
When the double input discrepancy auto recovery function is enabled, a
double input discrepancy detection error caused by closing a half-opened door
can be eliminated by fully opening the door again. For details on the double
input discrepancy auto recovery function, refer to the following.
