Process Interrupts - Siemens SIMATIC FM 353 Manual

Response after error
Leaving end position or traveling into working range after error
1. Acknowledge the error message!
2. Travel to the working range with the Jogging, Control, Incremental Relative or
MDI mode.
Rotary axis
The end position of MD
When traveling into the working range (e.g. end position was previously switched
off), the shortest path is always chosen.
If both default values are parameterized the software limit switches are inactive.

Process interrupts

Overview
Process interrupts are interrupts that quickly signal states in the current process to
the user program.
The appropriate setting in the machine data (MD5) specifies which signals are to
be quickly communicated to the user program.
Process-interrupt generation
The process interrupt is generated by way of machine data item MD5:
MD
5 Process-interrupt genera-
tion (data type - bit field)
Hint to the user
You must program the interrupt processing routine in OB40.
The prerequisite is that process-interrupt signaling must have been activated as
part of the environment definition (see Chapter 5).
