Event class 04h "CP detected error in data traffic CP - CPU"
04 03h Incorrect, unknown or illegal data type
(e.g. wrong parameterization of FB)
Remedy: Check program for incorrect parameterization of the FB.
04 07h Error during data transmission between CPU and CP.
Remedy: If fault indication persists, check whether function blocks you
have called in user program are parameterized correctly.
If error is indicated immediately after PowerON, no connection has yet
been set up to the CPU. In the case of the ASCII driver, the receiving
CP re-attempts data transfer until the data is transmitted to the CPU.
If fault indication is sporadic in the course of data transfer, the CPU is
temporarily unable to accept data. In the case of the ASCII driver the
receiving CP re-attempts data transfer until the data is transmitted to
the CPU.
04 08h Error during data transmission between CPU and CP (reception).
•
CPU is temporarily overloaded, request queued for repetition.
Remedy: Reduce number of communication calls
•
CPU data area temporarily unavailable for access, for example
because receive block is called too infrequently.
Remedy: Call the receive block more
frequently.
•
CPU data area temporarily unavailable for access, for example
because receive block is temporarily locked (EN = false).
Remedy: Check whether the receive block is disabled for too long.
... Event class 04h "CP detected error in data traffic CP - CPU"
04 09h Data cannot be received. Error during data transmission between CPU
and CP (reception). Request is canceled in 10s following multiple
attempts, because:
•
Receive block is not called
Remedy: Check whether your user program runs the receive block.
•
Receive block is disabled
Remedy: Check whether the receive block is disabled.
•
Access to CPU data area denied
Remedy: check that the data area to which the data is to be
transferred is available.
•
CPU data area too short.
Remedy: Check the length of the data area.
04 0Ah Error during data transmission between CPU and CP.
Data transfer canceled by RESET because:
•
Destination DB is not available
•
Destination DB is too short
•
RESET bit set at FB.
Remedy: Create destination DB in the user program or increase the
length of the existing destination DB, as applicable.
