DPV1 parameter data
The basic controller settings and functions can be set with the parameter data in the device master file (GSD file,
section 7.7 "Parameter data" on page 34).
Some PLC systems only allow you to change the settings in the GSD file when you create a new project. The
settings cannot be changed while the machine or system is operating.
The DPV1 protocol extension makes it possible to change these settings and functions without interrupting the
operation of the controller. The temperature coefficient for the heatsealing band, for instance, can be altered on
the PLC control unit during the validation process.
This acyclic service supports both reading and writing of the controller parameters. The parameter data can option-
ally be accessed by addressing the slot indexes. Since the controller does not store parameters transferred to it
in this way, you must remember to transfer all parameters that deviate from the static configuration again after
restarting the controller or the bus.
Please contact the manufacturer for more information about how your PLC system supports the
DPV1 protocol extension.
