8.2.10.3 Evaluating CBP diagnostic parameters
(For CBP2 diagnostic parameters, see section 8.2.10.6)
NOTE
Please note that, for types of unit with the older function classes FC
(CU1), VC (CU2) and SC (CU3), indexed parameter r731.i is to be
used appropriately instead of r732.i
In order to support start-up and for service purposes, the CBP stores
diagnostic information in a diagnostics buffer. The diagnostic information
can be read out with the indexed parameter r732.i (CB/TB diagnosis).
If two CBPs are inserted in the electronics box, the diagnostic area for
the second CBP begins in parameter r732 from index 33, i.e. an offset of
32 has to be added to the required index number for reading out the
diagnostic information of the second CBP.
