Configuring the PROFIBUS Master Chapter 4
4. Drag the input and output parameters to the Slot Location Grid
(Subscriber List) below the Bus Configuration window.
This view displays the slot number, configuration data, and starting input
and output addresses that will be assigned in the controller memory for the
MVI69-PDPMV1 Master. The Master uses this information to identify
and communicate with individual slaves on the network.
For this example, we will configure words for Ctrl/Stat & Ref/Fdbk as well
as the four input and four output datalinks. These input and output 16-bit
values are assigned to addresses within the MVI69-PDPMV1 Master’s
internal database. For each new slave added to the PROFIBUS network,
the PCB software automatically converts the input/output byte addresses
to input and output image addresses for the tag database in the
CompactLogix processor.
IMPORTANT Datalink modules must be configured in order:
Slot 2 = Datalink 1
Slot 3 = Datalink 2
Slot 4 = Datalink 3
Slot 5 = Datalink 4
If this is not done the 25-COMM-P will reject the configuration during
the startup of the Data Exchange.
When in Multi-drive mode this is also the case. The Drive 1...4 modules
should be added in order 1, 2, 3, 4 in the ascending slot numbers, or
the device will reject the configuration when trying to enter the Data
Exchange mode of operation.
