By default, the On/Offline indication is triggered by the link status. Other triggering options can how-
ever be specified in the optional system file ‘\onoffln.cfg’, which should be placed in the module root
and looks as follows:
The contents of this file can be redirected by placing the line ‘[File path]’ on the first row, and a file path
on the second.
File example:
[File path]
\my_settings\on-off-line_configuration.cfg
In this example, the settings described above will be loaded from the file ‘\my_settings\on-off-line_-
configuration.cfg’.
Note 1: The keys ‘[Timeout]’ and ‘[Commands]’ shall only be given if the On/Offline Trigger value is
set to ‘Modbus’.
Note 2: The settings in this file will be ignored if the application has issued the mailbox message
MB_ON_OFF_LINE_CONFIG. See “Advanced Fieldbus Configuration” on page 118.
