4 1: Function not supported, e.g. changing
the DP address of the DP/AS-i Link 20E
module by the DP master.
Check the configuration.
5 1: The DP master cannot interpret the
response from the DP/AS-i Link 20E
module correctly.
Check the PROFIBUS.
6 1: The DP/AS-i Link 20E detects an
incorrect parameter assignment frame
(e.g. incorrect length, incorrect ID number,
incorrect parameters).
Check the configuration.
7 1: The DP/AS-i Link 20E module was
assigned parameters by a different DP
master from the DP master that currently
has access to the DP/AS-i Link 20E
module.
This bit is always 1 if, for example, you
are accessing the DP/AS-i Link 20E
module with a PG or a different DP
master. The DP address of the parameter
assignment master is in the diagnostic
byte“Master PROFIBUS Address”.
