6.9.4 OB 83 - I/O_FLT2 - Insert / Remove Module
The CPU operating system calls OB 83 in following situations:
n after insertion / removal of a configured module
n after modifications of module parameters and download of changes to the CPU
during RUN
If you have not programmed OB 83, the CPU changes to STOP mode. You can disable/
delay/enable the insert/remove interrupt OB with the help of SFCs 39 to 42.
Each time a configured module is removed or inserted during the RUN, STOP, and
STARTUP modes, an insert/remove interrupt is generated (power supply modules, CPUs
and Bus coupler must not be removed in these modes). This interrupt causes an entry in
the diagnostic buffer and in the system status list for the CPU involved. The insert/remove
OB is also started if the CPU is in the RUN mode. If this OB has not been programmed,
the CPU changes to the STOP mode. Then system polls modules in seconds intervals to
detect insertion or removal. To enable the CPU to detect the removal and insertion of a
module, a minimum time interval of two seconds must expire between removal and inser-
tion. If you remove a configured module in the RUN mode, OB 83 is started. Since the
