Application example
Prerequisite: There is no direct I/O access in your user program.
If, for example, an enable sensor (f) in your system is defective and it continually
indicates a logical 0 to your user program, for example, via input 1.2, you can
bridge this sensor by forcing the input to 1, ensuring that your system continues to
operate.
!
Warning
However, because the sensor is out of operation, you must monitor the
functionality by different means to avoid injury to the operator and damage to the
machine.
