Power ON
The DP master is powered on. The master will change automatically to
RUN mode when the operating mode lever is in position RUN and the
parameters are valid.
STOP
In STOP mode the outputs of the allocated slaves will be set to 0 if the
parameters are valid. Although no communication will take place, the
master will remain active on the bus using current bus parameters and
occupying the allocated bus address. To release the address the Profibus
plug must be removed from the DP master.
STOP
→
RUN
In the RN position the master will re-boot: configuration data and bus
parameters are retrieved from the Flash-ROM.
An existing hardware
configuration is deleted by the boot procedure of the DP master.
To transfer a new hardware configuration you have to process Power ON.
At a STOP
→
RUN crossover the communication link to the slaves is
established. At this time only the R-LED will be on. Once communication
has been established by means of valid bus parameters the DP master will
change to RUN mode. The master interface displays this status by means
of the LEDs R and DE.
The DP master will remain in the STOP mode and display a configuration
error by means of the IF-LED if the parameters are bad. The DP master
will then be active on the bus using the following default bus parameters:
Default bus parameters: Address: 2, Communication rate: 1.5MBaud.
RUN
In RUN mode the R- and DE-LEDs are on. In this condition data transfer
can take place. If an error occurs, e.g. slave failure, the DP master will
indicate the event by means of the E-LED and it will issue an alarm to the
system on the next higher level.
RUN
→
STOP
The master is placed in STOP mode. It terminates communication and all
outputs are set to 0. An alarm is issued to the system on the next higher
level.
