5.2.3 Triggering of a remove/insert module interrupt
Triggering of a remove/insert module interrupt
In the event of a remove/insert module interrupt, the CPU interrupts processing of the user
program and processes the remove/insert module OB, e.g. OB 83. The event that triggered
the interrupt is entered in the start information of the remove/insert module OB.
Note
Parameter assignment error after removal/insertion
If you write data records from the user program to the modules of the distributed I/O, make
sure that these modules actually exist and are available. You can do this by evaluating
OB83. After inserting a module, OB83 is not called until the module has started up and its
parameters are assigned. This ensures that data record operations can be executed without
errors.
