5 Integration into the process automation system
For process control purposes it is important that the relevant process data are available in the PLC
map. The GSD file describes the number of input and output bytes of the Profibus Gateway SE. The
configuration software determines how to integrate the GSD file.
In regards to the data transmission, the temperature control unit is generally a slave. The Profibus
Gateway SE works with 9600 Bd on the RS-232 side. The interface parameters on the temperature
control unit must be set accordingly. Process variables may be E-grade and device dependent.
All provisions of the temperature control unit’s operating manual must be complied with.
5.1 Basic mode of operation of the Profibus Gateway SE
The Profibus Gateway SE constantly updates the process variables of the temperature control unit.
The actual process parameters are therefore always available when retrieving the process image.
The temperature control unit can immediately return the current process values when a Profibus
frame is received. On the other hand, the update loop sends the new process values to the tempera-
ture control temperature control unit. This data loop runs at about 300 ms per process value.
