Devices

Power-management devices are primarily measurement devices – they measure a wide variety of power-related data or control data describing what is happening at a device. This data can be read remotely (over a network) by power-management software, such as the PMCS DDE Server.

The data read by these devices is stored in registers, which are special, defined spots in the device’s memory. A list of these registers and their contents is called a register map. Figure 3 is an illustration of a register map. A client sends a request to the Server for data from a particular device. The Server knows the register map of the device and requests the register block containing the requested data.

The register maps for each device are programmed into the PMCS DDE Server. The Server is then able to transform a client application’s request for “kilowatt hours at North_Meter” into a request sent to that specific device for the contents of a specific register; the client doesn’t need to know which register contains what information, merely what information is needed from which device. The PMCS DDE Server takes care of the details, and after a request for data has been placed, the Server continues to monitor that data from the particular device, updating the client application with any changes to the data.

The register maps of the POWER LEADERTM family of devices and a variety of other devices are pre-configured in the Server. If you wish to use a device whose register map is not pre-configured, you need to supply the appropriate register information to the Server so it will know where in the device’s memory to get the information you are requesting. We’ll refer to these as generic devices since we don’t know what they might be. Defining new device types is detailed in Chapter 6, Advanced Options.
