Siemens S7-300 Interrupt, delay, Interrupt, diagnostic, Interrupt, process, Interrupt, status

Glossary

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.

See Interrupt, delay

Interrupt, diagnostic

See Diagnostic Interrupt

Interrupt, process

See Process interrupt

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.
