    The WattsOn-MCM may be purchased with as few or as many nodes as needed, and additional cards can be added at a later date if additional circuits are needed. Nodes are "hot-pluggable", meaning they can be added or removed without powering off the device, ensuring metering is not interrupted.

    2.1. Overall Procedure When working with the WattsOn-MCM device for the first time, especially if Wi-Fi is required, it is recommended to first setup and verify communication between the WattsOn-MCM and a PC or mobile device at a convenient location, before live voltages and current transformers are connected in their intended, final location.

  • Page 11: Network Discovery And Network Settings

    2.3. Network Discovery and Network Settings By default, the WattsOn-MCM is configured to automatically obtain its IP address via DHCP if available, and with AutoIP otherwise. If you are the network administrator, you may be able to determine the device’s IP address by consulting your router’s user interface.

The utility will automatically search for any Elkor devices present on the network. If the device does not show up within a Find few seconds, you can have the program send subsequent broadcasts by clicking the button.

    2.5. Node Installation Each node can meter up to three independent circuits, and up to 20 can be installed in a single WattsOn-MCM, giving a total of 60 independent circuits. Each node plugs in to one of the 20 PCI slots on the WattsOn-MCM, numbered 1 through 10 on the left side, and 11 through 20 on the right side.

    In some cases, the voltage may be tapped off of existing fuses or breakers. If this is not possible, Elkor recommends a 1A or lower fuse (fast acting) for protection of the installation wiring.

    3.1. Accessing the Web Interface To access the web interface for the WattsOn-MCM, open a web browser and direct it to the device’s IP address. (To discover the device’s IP address for the first time, refer to Section 2.3Network Discovery and Network Settings, p.

  • Page 16: Monitor Page

    This page allows you to configure custom data points to display. These data points can include any reading that the WattsOn-MCM provides, or it can be a sum, average, or other mathematical combination of any of those points. For example, it may be convenient to display the total current in channels 1 through 5, or the average power consumption of channels 2, 4, and 6.

    A Modbus slave device defines blocks of “registers” that contain information, each with a particular address. Each register contains a 16-byte field of data which can be read by the master device. The registers defined by the WattsOn-MCM are described later in this section.
