Technical data

When the system program calls OB 33, it transfers additional
information to ACCU 1 and ACCU 2 which provides more detail
about the first error to occur.

The identifier in ACCU-2-L is the level identifier (see Section 5.3) of
the time interrupt which caused the error.
Continuing program
execution
If you require the program to continue if a collision of time interrupts
occurs, either program the block end statement "BE" in OB 33 or
change the default in DX 0 so that the program is continued if a
collision occurs and OB 33 is not programmed.
After OB 33 is processed, the program is continued from the point at
which it was interrupted.
