Service
Description of the functions
Cyclic Data
Exchange
The module is part of the cyclic data exchange. The data coming
from the master are accepted and the data requested by the
master are transferred. The master controls this process.
Slave
Diagnostic
The slave transmits - after request of the master - the standard
diagnostic data, according to EN 50170.
Freez
If the slave gets a "freeze" message from the bus, it goes into the
freeze mode. All input data are kept. This means that the data,
which are presently in the input area are transfrerred via cyclic
data exchange to the master. If this area is changed later, the
data, being stored on the Profibus, will not be influenced. They
will only change, if a new message arrives in the freeze mode
from the master, or if the freeze mode is cancelled.
Unfreez
Cancels the freeze mode.
Sync
If the slave gets a "sync" message from the bus it goes into the
sync mode. All output data are kept. This means that the data,
which are presently in the output area are stable. If the master
transmits other data via cyclic data exchange, they will not be
transferred to the output area. This is only done, if a new sync
message arrives from the bus and the sync mode will be can-
celled.
Unsync
Cancels the sync mode.
Clear_Data Sets all output data to 0. That means, all memory cells, which
are located in the area of the output data, have the value 0 after-
wards.
Operating
mode
Behavior
Operate
The Profibus slave is part of the cyclic data exchange. Input data
are transferred to the master via bus and output data are made
ready for the master to transfer them.
Clear
The inputs are updated and the outputs are set to zero.
Stop
The slave is no longer part of the bus communication.
