Options for Specifying the Active Configuration
In the following example, two 1 6-channel digital modules and one 1 -channel
analog output module should not be part of the I/O Station. The modules are
part of the maximum configuration, but should be deactivated at this I/O
Station. An entirely different subgroup of the maximum configuration could
thus be active at another station. This means that I/O Stations with different
subgroups can be docked on Profibus and run with their individual
configurations.
There are three options for startup:
▪
Via DP/V 1
This option is only available for PBI002, and for hosts that support
DP/V
1 .
▪
Via DP/V0 with maximum configuration and configured empty spaces
Empty spaces remain free. The active configuration can be modified via
DP/V0 and the deactivation can then be undone from the configuration.
Proceed as follows:
1 . Deactivate the I/O modules in the hardware configuration and
download the hardware configuration.
2. In the hardware configuration select only the "PD-PCP x words"
module and download it. The actual connected structure is of no
importance here (at least one module must be connected).
3. Switch to cyclic data exchange and retentively set the
configuration connected to the station via index 6.
4. Enter configuration settings in the hardware configuration.
▪
The third option is particularly suitable for startup. All the hardware can
be plugged in together. You only need to transmit the hardware
configuration once on startup if "PD-PCP x words" is the only module
configured. Briefly switch to RUN state and transmit the data for index 6
and 8. The module can be clearly identified later by assigning an ID to
index 8.
The configuration for the maximum configuration can then be
completed.
