Set up a ControlLogix Meter Tag
For meters attached to ControlLogix device types, FactoryTalk EnergyMetrix software
communicates with PLC-5 or SLC 500 mapped tags in the ControlLogix controller. The
user must perform the tag mapping and configure meters by using the mapped addresses.
To communicate with ControlLogix native tags, use an OPC meter and the RSLinx
Classic OPC server.
To configure a ControlLogix tag, follow these steps.
1. In the Add a Meter Tag window, leave the Meter tag type set to Device.
2. Enter a Meter tag name.
3. If the tag corresponds to a Value Type, select a Value Type from the pull-down menu.
4. Enter a Log rate.
5. Type in the mapped Address in PLC-5/SLC 500 address format, for example F21:10.
6. Select the appropriate Tag format from the pull-down menu.
7. Select the Units, Number of decimals to display, Scale, Offset, and Rollover Value for
the tag as appropriate.
8. Click Save to save the new tag, or Cancel to exit without saving.
