  • Page 22: Communicating With A Power Patrol Meter

    COMMUNICATING WITH POWER PATROL METER There are a few things to determine before starting to communicate with your Power Patrol meter. Are you using BACnet or Modbus as your communication protocol? Will you use your own logger/controller to record measurements, or will you use the HeadStart software supplied with the meter to read real- time values? Is the data delivered over an RS-485 adapter or via the Ethernet? These determinations figure into how you set up the Power Patrol meter for operation.

  • Page 23: Setting The Network Address Switches

    Setting the Network Address Switches There are two rotary network address switches on a serial Power Patrol, labeled MSB (Most Significant Byte) and LSB (Least Significant Byte). These two switches are used to select the BACnet/Modbus address the client uses to communicate with the Power Patrol meter.

  • Page 24: Installing The Headstart Software And Communicating With The Power Patrol Meter

    Installing the HeadStart Software and Communicating with the Power Patrol Meter The HeadStart software is designed to let you easily configure the Power Patrol for different current transformers, check readings, and verify correct setup.

  • Page 27: About Ip Addresses

    IP address has been entered. (See below.) An additional option is to set the Power Patrol meter to DHCP and go to the router and assign a specific IP address to the MAC address that corresponds to the logger. In this way, if the lease does expire, the router will always assign the same IP number back to the logger.

    Pulse output is used to generate pulses for external devices such as data loggers that can accept pulses but do not have BACnet or Modbus capability. The Power Patrol can generate pulses based on accumulated value(s) such as system kWh, system kVARh, and system kVAh. When a pulse is generated by the meter, the orange LEDs will briefly flash, otherwise they will remain dark.

    Appendix D—VERIS H8035/H8036 Emulation The Power Patrol meter can be used as a direct replacement for the Veris, Inc. H8035/H8036 series of networked power meters. This mirroring of the Veris Modbus register assignments makes replacement with a Power Patrol meter simple. However, because the number of parameters that the Veris meters measure is less than half of what the Power Patrol can measure, the other Modbus registers described in the table need to be used to utilize the additional capabilities of the Power Patrol.
