Error Information
Error code
(W#16#...):
Explanation
0000 No error occurred.
0001 Not all system resources could be read because the SYS_INT target range you have
selected is too short.
8081 (only with MODE=2 or 3) You have assigned the value 0 to SI_ID.
8082 (only with MODE=1) You have assigned one of 0 different values to SI_ID.
8083 (only with MODE=0) You have assigned SI_ID a value other than at the preceding call
of the SFC with MODE=1 or 3.
8084 You have assigned an illegal value to MODE.
8085 SFC 105 is already being processed in another OB.
8086 Target area SYS_INST too small for a system resource.
8087 Target area SYS_INST does not exist in a DB.
