New OptoEMU Sensor DRs: Energy Monitoring Plus Demand Response

OptoEMU Sensor DR energy monitoring units with demand response capability

Smaller than our original OptoEMU Sensor 3V and with four signal relay outputs, the new OptoEMU Sensor DR (demand response) models give you great options for monitoring your firm's energy usage.

Use the new OPTOEMU-SNR-DR1 or OPTOEMU-SNR-DR2 if you don't need to connect directly to electrical panels using current transformers (CTs) (that connection requires the original OPTOEMU-SNR-3V) and if you need just one or two inputs for pulsing devices.

Sensor DRs give you:

  • Two pulsing inputs
  • Up to 64 data items from Modbus inputs (serial and Ethernet), including Modbus CT devices
  • Four signal relay outputs to signal building control systems or equipment to turn on or off. These outputs help you take advantage of demand response programs from your energy provider.
  • Choice of wired-Ethernet-only networking or Wired+Wireless
  • Smaller footprint and lower installation costs than the Sensor 3V

Like the OptoEMU Sensor 3V, the Sensor DRs monitor your energy usage in detail and then send energy data to:

  • An online software service, so you can see and analyze the data
  • Building and control systems using Modbus/TCP or OPC
  • Any SNAP PAC System
  • A PAC Display HMI
  • Company databases like Microsoft SQL Server and Access
  • Custom programs you develop using the free OptoEMU Sensor .NET Toolkit or XML-based data from the Sensor DR

The two Sensor DR models are identical except for their networking capabilities:
OPTOEMU-SNR-DR1—two independent wired Ethernet network interfaces plus a wireless LAN interface
OPTOEMU-SNR-DR2—two independent wired Ethernet network interfaces (no wireless)

Tech Tip: Time Savers for PAC Control


If you're someone who likes to save time, you probably already know about keyboard shortcuts like CTRL+S to save or CTRL+F to find. But do you know about the shortcuts in PAC Control? Here are a few that can speed your programming.

Keyboard shortcuts save keystrokes, give your mouse hand a break, and are a lot faster than using the trackpad/touchpad when you're on a laptop. Once you're in the habit of using them, you'll find they save a lot of time.

Edit menu showing keyboard shortcuts

Two kinds of keyboard shortcuts are built into Windows and work not only on PAC Control, but on most other Windows applications as well:

CTRL+ shortcuts—Hold down the Ctrl key while you press another key. All these shortcuts are shown on menus. For example, in the Edit menu, you see CTRL+X is Cut, CTRL+C is Copy, and so on. Not all menu items have CTRL+ shortcuts, though, so the next kind of shortcut handles many of the rest.

ALT+ shortcuts—Hold down the Alt key while you press another key. Use these shortcuts to open a menu and choose an item on the menu, without needing the mouse. Alt shortcuts are indicated by a short line underneath a single letter. To see them, open a strategy in PAC Control and click inside a chart; then press the Alt key by itself. You'll see underscores appear under one letter for each menu.

In the image below you see that ALT+F will open the file menu, for example, and ALT+C opens the Configure menu. Since the C is already used, you use ALT+t to open the Chart menu and ALT+p to open the Compile menu. (Don't worry about whether it's a capital letter or not; just hold down ALT and press the letter key.)

PAC Control menus with underscores indicating shortcuts PAC Control Configure menu showing ALT keyboard shortcuts

Once you've opened the menu you want, keep holding the Alt key and press another letter to choose the menu item. For example, you can see by the underscores in the Configure menu at right that you can choose configure I/O by just pressing ALT+C, then I. Note that you must click in a chart to do this, though; if you're in the Strategy Tree, it won't work.

In addition to these typical Windows shortcuts, PAC Control has a few more tricks to save time when working within a chart. You can see them all by clicking the blue Shortcuts link near the lower-right corner of the PAC Control main window.

Some really handy shortcuts are shown here. For example, just press + to zoom in on your chart, or press - to zoom out. To center on block 0, just press 0 (zero). When you're in a large chart, these shortcuts can really save you time.
