Setup and Commands Chapter 3
The Command.System_Registers data table, on page 368, is the command
interface. The value that is written into Command Word One or Command
Word Two identifies the command to be executed. The commands in Command
Word One are disabled if Configuration Lock is active. Some commands require
additional values to be written to specified elements of the
Command.System_Registers
data table. For example, a value of 18, Clear
Setpoint Logic Gate Accumulators, uses the value of Command.System_Register
data table element 3 to determine which logic gate accumulator to clear. The
power monitor ignores data table element values that are not associated with a
command. The power monitor rejects any attempt to select commands from
both Command Word One and Two simultaneously.
Chapters 4
…8 provide additional detail on commands associated with power
monitor functions.
Setup Using Custom Add-on
Profile
The Studio 5000® environment is used to configure I/O messaging between a
Logix controller and a PowerMonitor 5000 unit. An Add-on Profile is available
for the PowerMonitor 5000 unit and can be used with Studio 5000 software,
version 20 and later. The PowerMonitor 5000 unit Add-on Profile provides a
graphical user interface to modify configuration parameters, create intuitive
input and output tag names, and enables Automatic Device Configuration.
Automatic Device Configuration automatically allows the Logix controller to
manage device configuration data. Each time the Logix controller establishes a
connection with a device, the Logix controller downloads that configuration data
to the device. This download lets you save commissioning time by
preprogramming a device offline by using RSLogix 5000® or Studio 5000
software. Automatic Device Configuration is enabled by default in the
PowerMonitor 5000 Add-on Profile.
If you have a preconfigured PowerMonitor 5000 unit, or if you wish to configure
your unit by using the web interface, software, or Explicit Messaging, the AOP
gives you the option to disable Automatic Device Configuration. In the module
definition, the configuration method can be set to one of the following options:
• This Controller - Configure the unit by using the Module Properties
dialog box in RSLogix 5000 software. This option is the default setting.
• External Means - Configure the unit by using the web interface, software,
Explicit Messaging, or other means. The Module Properties dialog box
does NOT display subcategories specific to the device configuration.
Additionally, the connection type does not contain a configuration
instance. This option effectively disables Automatic Device
Configuration.
IMPORTANT The commands in Command Word One are disabled if an I/O connection is
active and the configuration instance exists in the Studio 5000 Logix
Designer application.
