Routing for ACS 600 The ACS 600 drive requires two fields of addressing. The first field is the
Modbus Plus node number, and the second field is the internal communication
buffer number in the drive. Valid numbers for the communication buffer field
are 1, 2, …, 8. The second field is mandatory.
Example: Routing from PLC A to the ACS 600 shown in Figure 6-1 below is
12.5.1.0.0. This example uses communication buffer 1.
Figure 6-1 Routing Example.
In this example, the bold numbers are node numbers for devices on Modbus
Plus network.
The PLC communicates to the drive through the Bridge device on node
address 12. The same communication result could have been done using other
communication buffers in the drive, for example routing 12.5.2.0.0 to
12.5.8.0.0.
Note: The global data can not be transferred through the Bridge. In the above
example the global data from the ACS 600 is available for PLC B, but not for
PLC A.
