CGCM-DLR Unit Software Interface
Chapter 6
Configuration Summary
•
The CGCM-DLR unit accepts Configuration data only when excitation
is disabled and all configuration data is in the correct range.
•
The CGCM-DLR unit accepts Unscheduled Write data regardless of the
excitation state provide that all Unscheduled Write data is in the correct
range.
Operating Interfaces
In normal operation, the ControlLogix controller shares operating data,
commands, and status through scheduled and unscheduled EtherNet/IP DLR
network messaging, by using the data tables that are automatically created when
the Add-on Profile is instantiated or created.
The overall functions and detailed content of the CGCM-DLR unit data tables
are described in the next section.
IMPORTANT
The message length can also be 64 bytes, which avoids writing the kWh,
kVARh, and kVAh presets.
IMPORTANT
You are responsible for initiating all unscheduled messaging through the user
program.
