Error in the SFB parameter configuration"
"Receiving a reaction message frame with error or an error message frame from the
communication partner"
Event class
Error code
Event Remedy
W#16#0902
Only for RK 512:
Memory access error
in the partner station (memory does not
exist)
With SIMATIC S5 as partner:
Wrong range in the display word
Data range does not exist (except
DB/DX)
Data range insufficient (except
DB/DX)
Check whether the partner is equipped with
the required data range and whether it is of a
sufficient size or check the parameters of the
called SFB.
Check the length specified in the SFB.
W#16#0903
Only for RK 512:
DB/DX access error
in the partner station (DB/DX does not
exist or too short)
With SIMATIC S5 as partner:
DB/DX does not exist
DB/DX too short
Illegal DB/DX no.
Permitted source range exceeded by
FETCH job.
Check whether the partner is equipped with
the required data range and whether it is of a
sufficient size or check the parameters of the
called SFB.
Check the length specified in the SFB.
W#16#0904
Only for RK 512:
Partner reports ”Job
type not permitted”.
Faulty partner behavior because the CPU
never outputs a system instruction.
W#16#0905
Only for RK 512:
Partner error or
SIMATIC S5 partner error:
Source/target type not permitted
Memory error in partner device
Error in partner CP/CPU
communication
Partner PLC is in STOP mode
Check whether the partner is able to transfer
the desired data type.
Check the partner’s hardware structure.
Switch the partner PLC to RUN mode.
W#16#0908
Only for RK 512:
Partner recognizes
synchronization error:
The message frame sequence is
disrupted.
This error occurs when you restart your own
or your partner’s PLC. This is a normal startup
behavior of the system. No remedies are
required. When operation is in progress this
error might occur as a result of previous
errors. Otherwise, you can assume faulty
behavior of the partner.
W#16#0909
Only for RK 512:
DB/DX locked in the
partner by coordination memory bit.
In the partner program: Reset the coordination
memory bit after you have processed the last
transmitted data!
The program: Repeat job!
W#16#090A
Only for RK 512:
Errors in the
message frame header recognized by
the partner: 3. Wrong instruction byte in
the header
Check whether the error is the result if
disturbances or faulty partner behavior. Prove
this with the help of an interface tester you
hook up into the data link.
W#16#090C
Only for RK 512:
Partner detects
wrong message frame length (length
total).
Check whether the error is the result if
disturbances or faulty partner behavior. Prove
this with the help of an interface tester you
hook up into the data link.
