(See section 8.2.10.7 for extended CBP2 diagnosis)
The CB parameters, P711 to P721, have two indices. The following
convention applies to this:
Index 1 is valid for the first CBP
Index 2 is valid for the second CBP
In order to determine which CBP is the first and which the second, see
Section 8.2.5 "Mounting methods / CBP slots".
With P711 / P696 (CB parameter 1), special diagnostic entries for the
CBP diagnostics buffer can be selected. If P711 / P696 is set to a value
not equal to zero during parameterization of the CBP by the converter,
telegram contents of the PROFIBUS-DP telegram are cyclically entered
into the CBP diagnostics buffer, depending on the set value.
The entries are made in rising sequence beginning with r732.9 (r732.10,
r732.11 etc.) in the same way as the corresponding useful data are
transferred via the PROFIBUS-DP, namely high-byte before low-byte,
high-word before low-word. The original entries (i.e. when P711 / P696 =
"0") are overwritten, beginning with r732.9.
Entries r732.1 to 732.8 retain their meaning.
Detailed knowledge of PROFIBUS-DP telegrams is needed in order to
evaluate these diagnostic entries.
It is only possible to set parameter P711 / P696 when the "Hardware
Configuration" function is being selected (P060 or. P052).
Parameter P711 / P696 is only to be set to a value other than zero for
diagnostic purposes because permanent transfer of diagnostic
information to the DPRAM reduces the data throughput rate of the CBP!
The original entries in parameter r732 / r731 are overwritten, beginning
with r732.9 / r731.9.
PMU:
P711 / P696 = 0
P711 / P696 = 1 to 26 Telegram diagnosis = ON
Telegram diagnosis = Off
