Data Table
Although the Unscheduled Write tag is contained in the Configuration tag in the
Logix controller tags, the Unscheduled Write must be read back from the
CGCM unit independently.
Message size depends on the unit’s firmware revision. 64 (FRN 2.x) or 76 (FRN
3.x or later) byte Message size from CNET to CGCM (Written to the CGCM
unit).
