Using the I/O

makeup of the I/O connection in a running system. The I/O connection with
the controller must first be disabled to allow changes to the respective Datalinks.

Depending on the controller being used, the I/O connection can be disabled by:

•

Putting the controller in Program mode

•

Placing the master in idle mode

•

Disconnecting the drive from the network

I/O Communication

The following example describes how to use PROFIBUS DPV0 I/O
communication for the CompactLogix controller for the PROFIBUS MVI69-
PDPMV1 Master.

I/O data transferred to and from the 25-COMM-P adapter nodes can be viewed
in the MVI69-PDPMV1 CompactLogix controller tags for the DPV0 cyclic
communication connections. See

Input Mapping in the MVI69-PDPMV1 on
