Figure 4-15 OB 40 start information: The event that triggered process interrupt for analog input
modules
You will find a description of OB 40 in the
System and Standard Functions
reference manual.
Triggering of a swapping module interrupt
Insert/remove-module interrupts are supported in DPV1 mode. The CPU interrupts
processing of the user program and processes the OB 83 diagnostic block instead. The
event that triggered the interrupt is entered in the OB 83 start information.
"Process interrupt lost" Diagnostics
Modules with a controller use the "Process interrupt lost" diagnostics.
The "Process interrupt lost" diagnostics are not currently available for the 2DI 24 V DC High
Feature and 4DI 24 V DC High Feature modules.
Note
Process interrupts should not be used for technological purposes (e.g. cyclical generation of
process interrupts).
If more than approximately 90 process interrupts are generated per second, process
interrupts may be lost.
