ET 200S IM 151-7 CPU Interface Module

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.
