Integrate Energy Data with Control Systems: OptoEMU 1.1 Is Here

OptoEMU Sensor energy monitoring unit

The OptoEMU Sensor energy monitoring unit tracks energy use in your facility and sends energy data to an online service so you can view it online.

Now you can also integrate this data directly with your SNAP PAC System and with other systems, too.

Version 1.1 of the OptoEMU Sensor updates the unit so you can use energy data in all these ways:

- Incorporate energy data in your PAC Control strategy. SNAP PAC controllers can read energy data from the Sensor's memory map (peer-to-peer).
- Show energy data in a PAC Display HMI.
- Send energy data to an OPC client or a Modbus/TCP system.
- Use energy data in a SQL database, to correlate it with utility expenses or for other purposes.

For details, see the new OptoEMU Sensor Communication Guide, form 1958.

OptoEMU Sensors shipping now have the new capabilities built in.
To update an existing OptoEMU Sensor, follow these steps:

  • 1. Go to the OptoEMU Sensor product page. Click the Downloads tab.
  • 2. Download three files: the Update File, the Data-Sharing Strategy, and the OptoEMU Sensor Manager Software.
  • 3. Click the Documents tab and download the updated User's Guide (form 1932) and the new Communication Guide (form 1958).
  • 4. Follow steps in the User's Guide Maintenance chapter to update your Sensor.
  • 5. Consult the Communication Guide for information on using energy data in the way you want.

If you have any questions while updating, please contact Product Support.

Tech Tip: PAC Control Spring Cleaning

PAC Control industrial control development software from Opto 22

If you've inherited a large PAC Control strategy from someone else or think you might have unused variables in your own strategy, here's how to clean them up. Unused variables take up unnecessary space and memory.

1. Open the strategy in PAC Control in Configure mode. In the Strategy Tree, double-click the Variables folder.

2. In the Configure Variables dialog box, scroll over to the right if necessary and look for the column titled Ref Count (see image below).

PAC Control variable reference counts

3. Click the column heading to sort the list of variables by Ref Count.

This column shows you how many times each variable is used in your strategy. If the Ref Count is zero, you may be able to delete the variable.

4. Before deleting any variable, check to see if it's used in a PAC Display project, a third-party HMI, or other program. Some variables may have been defined to use elsewhere, even though they're not used in PAC Control.

If the variable isn't needed, though, you'll save memory by deleting it.

This good advice for spring cleaning came from a recent OptoForum post: Clean up a big, over-grown strategy. If you have any cleanup tips, just log into your My.Opto account and add them to the thread. (Btw, make sure you're logged in so you can see images.)
