10.3 Settings and displays in the »Engineer«
On the Monitoring tab of the »Engineer«, you can set or display the following parameters:
Parameter Description
Reaction on communication
fault
( C13880/1 )
The response set here takes place if the PROFIBUS station ...
• does not receive a message from the master within the watchdog
monitoring time (displayed in C13882/1 ) if there is an active connection;
• recognises that it is not in the "Data_Exchange" status anymore.
Please see also the information on .
Clear process data
( C13885 )
Selection of the process data which the inverter will process in the event of
a PROFIBUS failure in order to maintain internal communication.
The process data sent last by the master can be used or the process data can
be set to zero.
Monitoring time: Data
exchange
( C13881 )
After the monitoring time set here has elapsed, the response set in takes
place for the data exchange.
• The value "65535" deactivates the monitoring function.
• The monitoring time set here must be smaller than the watchdog
monitoring time .
• A change in monitoring is effective immediately.
 Permanent interruption of PROFIBUS communication ( 81)
Monitoring time: Watchdog
( C13882/1 )
Display of the watchdog monitoring time determined by the PROFIBUS
master
• Monitoring starts with the receipt of the first telegram.
• When a value of "0" is displayed, the monitoring function is deactivated.
• A change in the watchdog monitoring time in the master is immediately
effective.
 Permanent interruption of PROFIBUS communication ( 81)
Set ext. diagnostic bit upon
( C13886 )
Bit-coded selection of the error responses in the standard device causing the
external diagnostic bit ("diag bit") to be set (see PROFIBUS specification; bit 3
of byte 1 of the DP diagnostic messages).
• The diagnostic bit is sent to the PROFIBUS master where it is evaluated
separately.
• The diagnostic bit is always set when a system error occurs.
• The Lenze setting "0" means that the diagnostic bit is not set for the
following error responses.
• An advanced diagnostic message is always sent.
