CGCM-DLR Unit Configuration
Chapter
4
Electronic Keying
Although the CGCM-DLR unit does not physically reside in a ControlLogix
chassis, electronic keying provides protection against module mismatch.
You must choose one of these keying options for the CGCM-DLR unit during
module configuration:
•
Exact match - all parameters that are described must match or the inserted
module rejects a connection to the controller
•
Compatible module - provides for different major or minor revisions of
CGCM-DLR firmware
•
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-DLR unit is replaced with an incompatible unit.
Manually Configure a
Static IP Address
When the unit thumbwheel switches are set to 99 and read after a power-up or a
reset, the IP address can be manually configured in the Logix Designer
application. Here is an example procedure to configure manually a static
IP address from a private network to an Enterprise network. In this example, the
CGCM-DLR IP address is changed from 192.168.1.114 to 10.90.172.72.
This procedure is performed in the Logix Designer application and assumes the
following:
•
The 1407-CGCM-DLR module has previously been created (see
the New 1407-CGCM-DLR Module in the I/O Configuration on
page 76
).
•
The thumbwheel switches have been set to 99 and power is cycled on the
CGCM-DLR unit.
•
You are online and in Remote Program mode in the Logix Designer
application.
ATTENTION:
Be cautious when using the disable keying option; if used
incorrectly, this option can lead to personal injury or death, property
damage or economic loss.
