4. Verify the Meter tag type is Device.
5. Change the Meter tag name.
For this example, enter Boiler House Natural Gas Usage.
6. Choose a Value type.
For this example, choose Natural Gas Usage.
7. Verify the log rate.
The log rate is set to the default log rate of meter’s
assigned group. It is typically the utility demand interval
rate. Refer to the FactoryTalk EnergyMetrix software
help for details.
8. Enter an L2x controller address.
Refer to the Energy Data Worksheet for the L2x PLC-5
type address.
FactoryTalk EnergyMetrix software communicates with
PLC-5 or SLC 500 mapped tags in ControlLogix
controllers so the address format is Fx:x.
In this example, the Boiler House Gas meter tag, Boiler
House Natural Gas Usage, is assigned to the PLC-5 tag
F10:0.
This F10:0 tag is then mapped to the L2x_EnergyTotals
[0] tag in the ControlLogix controller as configured on
page
86.
9. Choose a tag format.
For this example, choose 32-bit Floating Point for this
analog tag.
10. Fill in the appropriate scale and offset values.
For this example, the scale is 1 and the offset is 0 because the energy Add-On Instruction has already scaled the tag
units.
11. Enter appropriate rollover value, which is 10 million when using the energy Add-On Instructions.
12. Click Save.
13. When done, click the Return to meter screens
link or the meter tag.
