WECK-FE (Collision of Time
Interrupts)
If a particular time interrupt OB is requested before its last request has
been completely processed, the system program recognizes a collision
of time interrupts and calls organization block
OB 33, if it is loaded,
or the CPU goes to the STOP mode. See Section 4.5.2.
ACCUs 1 and 2 contain additional information that defines the error
in greater detail.
Error identifier
ACCU-1-L ACCU-2-L
Explanation
1001H 0016H Collision of time interrupts in OB 10
(10 ms)
0014H Collision of time interrupts in OB 11
(20 ms)
0012H Collision of time interrupts in OB 12
(50 ms)
0010H Collision of time interrupts in OB 13
(100 ms)
000EH Collision of time interrupts in OB 14
(200 ms)
000CH Collision of time interrupts in OB 15
(500 ms)
000AH Collision of time interrupts in OB 16
(1 sec)
0008H Collision of time interrupts in OB 17
(2 sec)
0006H Collision of time interrupts in OB 18
(5 sec)
Note
The identifier in ACCU 2 is the level identifier of the time
interrupt that caused the error.
If you do not program OB 33, the CPU goes into the stop mode.
You can, however, program
DX 0 so that the program is
continued when a collision of time interrupts occurs although you
have not programmed OB 33.
A second call for the already active error program processing
level "collision of time interrupts" does not lead to a double call
error (DOPP).
