Rockwell Automation 22-COMM-D DeviceNet Adapter - Manual (Page 33)

Configuring the Adapter 3-9
Cyclic and Polled data exchanges are configured in the scanner, so you
only need to set the I/O configuration in the adapter. COS data exchange
must be configured in both the adapter and the scanner. You need to set
the I/O configuration and COS parameters in the adapter.
To use COS (Change of State) data exchange
1. Set the bits in the Logic Status word that should be checked for
changes in Parameter 12 - [COS Status Mask]. The bit definitions
for the Status Mask will depend on the drive to which you are
connected. Refer to its documentation.

PowerFlex 4-Class HIM (22-HIM-*)
2. Set the amount of change to the Feedback that is required to trigger a
Change of State message in Parameter 13 - [COS Fdbk Change].

The adapter is now configured for COS data exchange. You must
configure the scanner to allocate it using COS (

the Scanner ).
