DeviceNet Communications Interface 

Change Of State (COS) and Cyclic Outputs 

A device only sends a Change of State (COS) / Cyclic Output message when either data has 
changed or after a pre-defined timer expiry (heartbeat). Both the mode and cycle time are 
defined by the PLC. 

The 890 supports a single Assembly Object for COS / Cyclic Output. This is configured using 
DSE. 

 

 

The example above defines an Assembly Object consisting of 1 Output register. The output size 
is 1. The matching PLC configuration is, for Change of State: 

 

 

If the DSE configuration does not contain a DNET function block, the Assembly Object 
defaults are the same as for Polled Outputs.
