Bits
8-11
Meaning of the error bits
0 No error.
If bit 3 "job complete with error" is nevertheless set, this means that the CP has
set up the job again following a cold restart or RESET.
1 Wrong type specified in block call (QTYP/ZTYP).
2 Memory area does not exist (e.g. not initialized)
3 Memory area too small.
The memory area specified in the HDB call (parameters Q(Z)TYP, Q(Z)ANF,
Q(Z)LAE) is too small for the data transmission.
4 Timeout (QVZ).
Acknowledgement from the memory cell is absent during data transfer. Remedy:
check and if necessary replace the memory submodule or check and correct the
source/destination parameters.
5 Incorrect parameters assigned to status word.
The parameter "ANZW" was specified incorrectly. Remedy: correct the
parameter or set up the data block correctly in which the ANZW is to be located.
6 Invalid source/destination parameter.
Parameter ID "NN" or "RW" was used or the data length is too small (=0) or
longer than 128 bytes. Remedy: use the correct Q(Z)TYP parameter; "NN" and
"RW" are not allowed for this type of data transmission. Check the data length.
7 Local resource bottleneck.
There are no data buffers available for processing the job. Remedy: retrigger the
job, reduce the CP load.
B Handshake error.
The HDB processing was incorrect or the HDB monitoring time was exceeded.
Remedy: start the job again.
C System error !
Illegal service code service_code or error in system program.
Remedy: check service_code or inform Siemens service.
D Data field blocked!
The data transmission is or was disabled during HDB execution (control bit
disable/enable in status word set to disable).
E free
F Job or channel not programmed !
Programming error or incorrect HDB call (parameter SSNR/ANR).
Remedy: program job number (ANR) as "free channel" (type:FREE) or correct
SSNR/ANR for HDB call.
