Interrupt, delay
The delay interrupt belongs to one of the priority classes in SIMATIC S7 program
processing. It is generated on expiration of a time started in the user program. A
corresponding OB will be processed.

Interrupt, status
A status interrupt can be generated by a DPV1 slave and causes OB 55 to be called on the
DPV1 master. For detailed information on OB 55, see the Reference Manual System
software for S7-300/400: System and Standard Functions.
Interrupt, time-of-day
The time-of-day interrupt belongs to one of the priority classes in
SIMATIC S7 program processing. It is generated at a specific date (or daily) and time-of-day
(e.g. 9:50 or hourly, or every minute). A corresponding OB will be processed.
Interrupt, update
An update interrupt can be generated by a DPV1 slave and causes OB56 to be called on the
DPV1 master. For detailed information on OB56, see the Reference Manual System
software for S7-300/400: System and Standard Functions.
Interrupt, vendor-specific
A vendor-specific interrupt can be generated by a DPV1 slave. It causes OB57 to be called
on the DPV1 master.
For detailed information on OB 57, see the
Reference Manual System Software for
S7-300/400: System and Standard Functions.
