ABB AC31 - 1.3.2.6 Diagnosis

Fig. 13: CS31 slave
The module address must be set on each CS31 slave. Specify the same module address that
has been selected with the DIP switches.
Set the CS31 slave type (analog/digital):
Fig. 14: CS31 bus slave configuration
The data must be configured in the tree structure under the CS31 bus slave. Information about
the number of input and output data can be obtained from the respective documentation of the
CS31 bus slaves.
If the data represent bipolar values (e.g. voltage from -10 V…+10 V), the use of
the data type INT is appropriate. In case of unipolar values (e.g. current from 0
mA…20 mA), the data type WORD can be used.
1.3.2.6 Diagnosis
For the diagnosis of the CS31 bus, various mechanisms are available in the CS31 bus master
of the devices 07KT98-ARC-AD, 07KT98-ARC-DP-AD, 07KT98-ARC-ETH-AD, 07KT98-ETH-
DP-AD and 07KT98-ARC-ETH-DP-AD:
● Diagnosis via the function block CS31_DIAG
● Diagnosis system of the AC500 series
For further information on both mechanisms, please refer to the AC500 documentation. Below,
only a few special diagnosis functions of the AC31 adapter are addressed.
In the 'State' column, the variable byStateDiag of the structure strCS31_DiagOneModule is
indicated for every CS31 bus slave.
