8.4.6.3 Evaluation of the CBC diagnostic parameter
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
The CBC stores this information in a diagnostics buffer to support start-
up and for service purposes. The diagnostic information can be read
out with indexed parameter r732.i (CB/TB diagnosis). This parameter is
displayed as a hexadecimal. The CBC diagnostics buffer is assigned as
follows:

Counter: telegrams received without faults/errors r731.2 r732.2
