PROFIBUS
PT50 can be equipped optionally with a PROFIBUS-DP-Interface. The necessary GSD-file for develop-
ment tools is available as PEH_002.gsd.
PT50 represents a modular Profibus-DP-Slave at the PROFIBUS. It can be configured either in i_CS
(carburizing) or in i_NS (nitrating) mode., Nitrocarburieren, can be driven. The data structure is depend-
ent on the selected configuration.
Properties:

The Pfofibus-address is set manually at the PT50 or with help of the service-program.

The baud rate is recognized automatically, the profibus standard values are in the range from
9600Bd … 12 Mbauds..

Freeze - and Sync-operation are not supported because these are not meaningful for PT50.

With the project planning by means of a GSD-file, the configurations „i_CS “and „i_NS “ are se-
lectable. PT50 gets ready automatically in the Configuration-phase for the chosen configuration.

The SPS can always read the at the input values from the PT50. Output data (setpoints and pro-
cess parameters) will be adopted only in Remote mode.

faults are transferred as external diagnostics.
Attention! Because Input and output data are transferred constantly with profibus, the master must al-
ways prepare all output data comprehended in the chosen configuration (setpoints and process pa-
rameters), even if is they are constant. The take over of the setpoints requires Remote operating mode.
Further information to the operation of the PT50 with MODBUS-Interface is available in a separate doc-
ument.
DP-Status
Shows the status of the PROFIBUS-DP connection:
Status Explanation
Wait_PRM The PROFIBUS-DP-Interface waits for the information of the communication-
parameters from the busmaster..
Wait_CFG The PROFIBUS-DP-Interface waits for the selection and checkup of the data-
configuration through the Busmaster.
DATA_EX The connection was built up successfully, data are exchanged.
Baud rate
Baud rate of the PROFIBUS-DP – connection
Act.Config.
From the Busmaster ordered and from the PT50 of confirmed data-configuration.
Configuration Application
i_CS carburizing furnaces with Cp-control or similar
i_NS Nitrating- and nitrocarburizing furnaces
Address
