6.25 OB 223: Comparing Restart Types

Function

If you call OB 223 in multiprocessor operation, the system checks

whether the restart types of

all CPUs involved are the same.

Note

OB 223 must only be called when all the CPUs have completed

their start up.

If start-up synchronization is active (DX 0) this is guaranteed by

calling OB 223 in the RUN mode.

If start-up synchronization is

inactive this must be achieved by

other means, e.g. delayed OB 223 call.

Parameters

none

Result

Error messages in the event of deviating restart types

Possible errors

If the restart types of all the CPUs participating in multiprocessor

mode are not the same, the CPU in which OB 223 is processed detects

a runtime error.

OB 31 is then called.

If OB 31 is not loaded, the CPU goes to the STOP mode with the LZF

error message. Its STOP LED flashes slowly. The other CPUs also go

to the STOP mode, their LEDs show a steady light.

Error IDs

When OB 31 is called and the CPU is in the STOP mode, the error ID

1A3BH is entered in ACCU-1-L.
