DP/AS-Interface Link 20E
Release 11/2002
C79000-G8976-C138–04
Byte Remedy Value/meaning Bit
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”.
Station Status 2
Byte Bit Value/meaning
1 0 1: The DP/AS-i Link 20E module must have parameters reassigned by the DP
master.
1 1: A static diagnostic message exists.
2 1 :This bit is always ‘1’ with the DP/AS-i Link 20E module.
3 1: The response monitoring of the DP/AS-i Link 20E module is activated.
4 1: The DP/AS-i Link 20E module has received the“FREEZE” control command.
5 1: The DP/AS-i Link 20E module has received the“SYNC” control command.
6 0: This bit is always set to ‘0’.
7 1: The DP/AS-i Link 20E module is deactivated, in other words it is not taking
part in the current processing.
