DPV1 parameterization: connection to an S7 PLC

So-called DPV1 parameterization allows asynchronous
parameterization messages to be exchanged in parallel
with PROFIBUS DP mode with cyclic data exchange
between the Master module and the T12HP.
Alternatively, they can be sent from the DP Master (for
example the PLC, the so-called Class 1 Master), or even
in parallel from a second, so-called diagnostic Master (for
example the programming unit, the Class 2 Master).
If the customer wishes to make use of DPV1 parameteri­
zation, the relevant service routines must be called in the
PLC. A basic distinction is made between setting up and
releasing a connection and between read and write
access to parameters. The various parameters are
addressed by the so-called index and slot numbers.
The T12HP maps these index numbers to the commands
described in the Operating Manual (see Chapter 5, start­
ing on page 28).
More detailed information on DPV1 mode can be
obtained from the manufacturer of the Master module.
