5.4 Diagnostics
For rudimentary diagnostics of the connected bus two sub func-
tions are available:
• Display bus nodes
• Display bus parameters
Before the diagnostics functionality is used, a valid station must
be created and a plausible bus configuration set.
5.4.1 Bus members
A list of all available nodes at the bus will be generated by clicking
the button ‘Read.’
With activating the option ‘Read MLFB number’ the order numbers
of all devices supporting this function will be displayed too.
The possibility to detect all connected nodes depends on the
parameterization of the PG/PC Interface. It is recommended to
enable auto baud functionality at MPI and PROFIBUS.
5.4.2 Bus parameters
If it is possible a list of all bus parameters will be displayed by
clicking the button ‘Read.’
The possibility to detect the bus parameters depends on the
parameterization of the PG/PC Interface.
The “Station type” column
lists both active (master)
and passive (slave) st
a-
tions.
The NETLink unit being
used will be shown as a
Station address.
