6.2 Diagnostics with a Class 2 Master
A Class 2 master can be used for installation and diagnostic purposes.
An example of a Class 2 master is a PG Programmer or a PC fitted with a CP5412 communications processor and
running the COM ET 200 software package. Note that for this to function correctly, the IM308B/C must be
configured to allow a Class 2 master to be connected to the bus. Information on how to achieve this and on how to
control a slave device from the COM ET 200 software are included in the COM ET 200 software manual.
Note that the Class 2 master may also be used without the IM308B/C being enabled on the bus. The Class 2
master may also be connected directly to the D-type connector on the CB15/CB155 if desired.
When using a Class 2 master to control a slave device, the PROFIBUS watchdog is not enabled. This
means that if no Class 1 master (e.g. a PLC) is enabled and the Class 2 master is disabled or the bus
is disconnected while the inverter is running then the drive will continue to run.
WARNING
In installation/test mode, the Class 2 master assumes the function of the Class 1 master for the selected station.
The exchange of user data with the selected slave does not take place cyclically.
