Comment
Valid values are Exact Match, Compatible Module (default), or Disable Keying.
Exact Match
When Keying is set to Exact Match, the module accepts the connection only when the
module firmware major and minor revision numbers are the same as the Major and
Minor Revision numbers in the Revision parameter.
Compatible Module
When Keying is set to Compatible Module the module accepts the connection when
the module firmware, as compared to the Revision parameter Major and Minor
Revision numbers, is:
• The same or higher Major Revision and
• The Minor Revision is as follows:
Disable Keying
When Keying is set to Disable Keying the keying attributes are not considered when
attempting to communicate with the module.
Electronic Keying can be edited while online or offline. For more detailed information
on Electronic Keying, see Electronic Keying in Logix5000 Control Systems Application
Technique, publication LOGIX-AT001.
Displays the connection type for your module. Currently the only choice is Data.
Specify if the module is powered by one or dual power supplies.
When powered by dual supplies (redundant mode), the module monitors each power
supply input and signal its status by using bit 15 of input tag member
AuxProcesorStatus.
The status bit is set (1) if this parameter is set to Redundant (1) and either of the
supply voltages is less than 17V DC.
Redundant power is required for all API applications (ComplianceMode not equal to
"None").
Using External Redundant Supplies
If the application requires API-670 compliance and power redundancy is being
implemented externally, then it is necessary to connect power to both power inputs
on the module. If power is landed to only one input, and the Power Supply mode is
set to Redundant, then a fault indication is given.

Configure the 1444 Dynamic Measurement Module
– If the Major Revision is the same, the Minor Revision must be the same or
higher.
– If the Major Revision is higher, the Minor Revision can be any number.
ATTENTION:
Be cautious when using Disable Keying. If used incorrectly, the module
configuration may not match the configuration in the Profile and/or
returned data and status information may be incorrect or
misinterpreted.
We strongly recommend that you do not use Disable Keying.
If you use Disable Keying, you must take full responsibility for
understanding whether the module can fulfill the functional
requirements of the application.
IMPORTANT To change Electronic Keying parameters online requires that
the connection to the module is broken and re-established.
Consequently:
• Until a new connection is established module I/O is
interrupted.
• When the connection is dropped a "Failed to Modify
Properties" dialog box is presented.
