CGCM Unit Configuration #HAPTER
•
Compatible module - a unit with host firmware major revision 3 or 4
functions as a unit with host firmware major revision 2 if so configured
when the new module is created
•
Disable keying - the inserted module does not reject a connection to the
controller
An I/O module that is connected in a ControlLogix system compares the
following information for itself to that of the original configuration:
•
Vendor
•
Product type
•
Catalog number
•
Major revision
This feature can prevent the inadvertent operation of a control system if a
CGCM unit is replaced with an incompatible unit.
$EVICE3ETUP
You must configure the CGCM unit for the unit to function. Configuration tabs
in the module set-up screen divide the required information into sub-categories.
Evaluate the system and generator information to determine the appropriate
configuration settings and use the configuration tabs to enter the settings.

The configuration tabs provide a simple way for you to enter and edit CGCM
unit configuration parameters. Changes you make to the configuration are not
always immediately sent to the unit. The configuration data is stored in two
controller tags in the ControlLogix controller, the Configuration tag and the
Unscheduled Write tag.
Refer to Chapter 6 for details on these data tags.
The Unscheduled Write tag contains the parameters from the Gain tab along
with the Line Drop Voltage Compensation from the Voltage tab. The
Configuration tag contains all other CGCM unit configuration parameters.
Configuration data from the Configuration tag is written automatically to the
CGCM unit only when excitation is not enabled and one of two following
conditions occur:
•
A connection is first established to the CGCM unit
•
You change the configuration with the configuration tabs
