Chapter 4 Configuring the Profibus Master
4.
In the treeview, click ‘+’ to expand the slave you added.
This action opens a list of device configuration values. The window above
shows the possible input/output configuration values for a 20-750-PBUS
Slave. The Datalinks (1-16) allow the assignment of configured drive
parameters to be included in the Profibus DP I/O data frames that are
transferred between the ControlLogix controller and the PowerFlex 750-
Series drive.
5.
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
MVI56-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. These
input and output 32-bit values are assigned to addresses within the
MVI56-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 ControlLogix processor.
6.
Likewise add as many modules as required.
