Functions of the IM 151/CPU
5-7
ET 200S Interface Module IM 151/CPU
A5E00058783-01
Note
Due to insufficient battery backup, force requests do not survive after power
off/power on.
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.
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.
