Hardware interrupt

Diagnostics: Short circuit

The input delay applies to "0" to "1" and to "1" to "0".

Short circuit of the sensor supply.

Can only be parameterized for the IM151-1 High Feature interface module and the IM151-7 CPU

If the wire break check is activated, all the unused inputs must be stabilized to prevent them from triggering

(3, A4, 7, A8) and the free input. The resistor must provide at least 0.5 mA of input current (see "Sensor

Switching" in the table of technical specifications). This ensures that sufficient current is flowing to prevent

wire break detection.

A sensor must provide a minimum of 0.5 mA in the off state (otherwise a wire break is detected in the off

state). Alternatively, a resistor can be connected parallel to the sensor terminals (the current must be at

least 0.5 mA).
