Chapter 9 Communication
Refer to Appendix A for the content of these data tables. The
<ModuleName>:C tag is populated with default configuration values. When
the connection is opened, the configuration tag is written to the power monitor
and over-writes any existing configuration. In most cases this restores the default
Metering_Basic and SystemGeneral configuration of the power monitor.
With an exclusive owner connection active, the following capabilities and
restrictions apply:
• Only the owner controller is permitted to modify the power monitor
configuration. You can use the Logix Designer application and the module
properties dialog box to view and edit the power monitor configuration,
including the native EtherNet/IP communication parameters. Attempts to
change the configuration through the web page or other applications is
rejected with an ‘exclusive ownership conflict’ error.
• The owner controller can read the Input tag elements in its logic and write
the Output tag elements in its logic.
• You can use Logix Designer application online with the owner controller
to force inputs and outputs configured for native EtherNet/IP control in
the power monitor.
• If the connection is lost, the Default_State_on_Comm_Loss parameter
determines the behavior of each output.
Listen Only
If an Exclusive Owner connection exists, additional controllers can establish
Listen Only connections that permit the controller to read data from the power
monitor's Input data tables. You can also view (but not edit) the power monitor's
parameters from the module properties dialog box.
To add a Listen Only connection, the Exclusive Owner connection must be set to
Multicast and both connections must be set to the same RPI.
When you first set up a Listen Only connection, the following module-defined
controller tag is created: <ModuleName>:I, the Input tag, mapped to the
ScheduledData.Input table.
