Cause of error
Power failure in an S7-400 expansion unit
•
Failure of a DP/PN segment
•
Failure of a coupling segment: Missing or defective IM, inter-
•
rupted cable
Communication error:
Time synchronization
•
Access to DB when exchanging data via communications func-
•
tion blocks
The execution of a program block was canceled. Possible reasons
for the cancellation are:
Nesting depth of nesting levels too great
•
Nesting depth of master control relay too great
•
Nesting depth of synchronization errors too great
•
Nesting depth of block call commands (U stack) too great
•
Nesting depth of block call commands (B stack) too great
•
Error during allocation of local data
•
Such errors cannot occur with blocks from a SIMATIC PCS 7 li-
brary.
The Runtime software could not be completely licensed (internal
error).

•
Range length error
•
Range error
•
Alignment error
•
Write error
•

•
Counter number error
•
Block number error
•
Block not loaded
•
Such errors cannot occur with blocks from a SIMATIC PCS 7 li-
brary.
Error in the compiled user program, for example, illegal OP code or
a jump beyond the block end
Such errors cannot occur with blocks from a SIMATIC PCS 7 li-
brary.
