BTSMADAP & BTS_ZV Function Modules 5-5
Bit Cause of Fault Troubleshooting
9 Cascade number not per-
mitted with manual diag-
nostics.
Parameter P2 of DIAG500E module
is not within permitted range be-
tween 1 and 64.
→ Modify parameter settings.
8 Invalid number of cascade
sequences.
Parameter P3 of DIAG500E module
has a value higher than 64. You cannot,
however, process more than the maxi-
mum of 64 cascade sequences.
→ Modify parameter settings.
7 Fault in system area (sys-
tem instruction).
This bit indicates that too many system
instructions (e.g. LAD and TAD) are
being used in the entire PLC program.
→Reduce the number of system in-
struction calls or utilize sequential call
coordination.
In this context, see also the manual
entitled CL500 System Instructions,
order no. 1070 072 068.
6 Structural fault in cascade
sequence jump distributor.
The DIAG500E module has detected
a structural fault in the jump dis-
tributor for the cascade sequence.
The cause may be that the step
sequence in the jump distributor
does not correspond to that in the
step program.
→Modify the step sequence either in
the cascade module or in the jump
distributor.
5 Data field address (P7) too
high.
The data field base address has
been defined too high, denying the
requested substations needed space
in the data field area.
→Define a smaller start address.
4 Too many conditions in the
branch to be diagnosed.
In the BEFA command output or
WSB step-on condition branch, the
maximum number of 64 conditions
per BEFA or WSB allocation was
exceeded.
→Divide the branch into several
subbranches.
