Hello,

I'm currently converting a program for and old S5-115U CPU 994B to S7-1500. The S5 came with the hardware interrupt input module 434-7LA12.

I've already had a read of the manual for that module and found out that it occupies two bytes of inputs and two bytes of outputs.

First output (eg. IB8) gives the actual status of inputs and second byte (eg. IB9) gives the information which input triggered the interrupt.

Configuration of inputs in my project is as follows:

I8.0 / I9.0 - Positive Edge

I8.1 / I9.1 - Positive Edge

I8.2 / I9.2 - Negative Edge

I8.3 / I9.3 - Negative Edge

Inputs I8.4 - I8.7 not usedThank You!
