Creating a meter channel

A meter channel can either be an interval channel or a register channel.

Interval Channel

An interval channel stores a data quantity recorded by a metering device for a set frequency. For example, with a 15-minute interval, register values are recorded every 15 minutes. The time between readings is both predictable and exact. The interval length, also called the interval frequency, is the number of minutes that elapse between recording register values. Interval lengths divide evenly into 60, with the exception of the 1440-minute interval that represents 24 hours.

Creating an Interval Meter Channel

1. Configure the following parameters:

   Channel Number. Select or enter the service point channel number.

   Description. Defines the description of the interval.

   UOM. Defines the reading unit of measure (UOM). The UOM must match a UOM ID that is configured in IEE.

   Interval Length. Defines the length of time between a meter interrogation.

   Rolling Interval Length. Defines the length of time over which to average the demand, and allows you to smooth demand. Rolling demand may be required for billing purposes. For example, if the export is for billing, and the customer contract specifies billing on a 60 minute rolling demand for data that is metered in 15 minute intervals, set the Rolling Interval Length to 60. When you export the data, there is an interval value every 15 minutes. However, the value is an averaged demand value over 60 minutes that ends at the time stamp for each 15 minute interval. In this case, the averaged intervals are the current interval plus the three previous intervals.

   KE Multiplier. Defines the factor used to convert interval reads into engineering units. The KE multiplier applies only to interval meter reads. The meter KE is the watt hour per pulse value programmed into the meter or recorder. When applying a pulse multiplier you are applying a factor to convert pulses of energy to kilowatt usage per hour, which is the pulse constant.

   Source Reactive. Select the UOM.

   Contains Meter Read. Select the checkbox to continue entering the settings defined in the meter.

   Meter Channel Offset. Defines the number by which to offset the interval channel number. If the interval channel contains a meter read, the register number of the associated register channel is set by adding this offset value to the interval channel number.

   Meter Read UOM. Defines the unit of measure set in the meter.

   Number of Dials. Defines the number of dials that are used for the meter read. Used to interpret the meter (start/end) read of the interval stream.

   Number of Decimals. The number of decimals used for formatting the reading captured.

   Truncation Factor. Defines the number of decimals truncated when converting dial readings into engineering units. Default value is zero.

   Encoder Type. Defines the encoder type of the register. Limited to 10 characters.

   Display Multiplier. Defines the display multiplier of the meter (start/end) read of the interval stream. This value is used to calculate the meter multiplier (MM) with the following formula:

   CT * PT * DisplayMultiplier

   The MM is used to determine how to evaluate the start/end read. These 'register' reads are currently assumed to be raw, and the MM is applied only for evaluation for processes such as validation.

   Sequence. Defines the sequence of reading the register within the meter.

   Display Code. Defines the display code for the interval reading.

Register Channel

A register channel records a single value quantity. A single value quantity is one that is not recorded on a precise timer interval or frequency; the time between readings is irregularly-spaced and not predictable. Register quantities usually represent total or summary values over a much longer time period than interval values.

Creating a Register Meter Channel

1. Configure the following parameters:

   Description. Defines the description of the register. Limited to 100 characters.

   Display code. Defines the display code for the register reading.

   Decode Name Type. Defines the register decode name type of the register. ServiceModeXi specific - MV90 specific information, matches name in decode file.

   MV90 Register Type. Defines the MV90 register type of the register. ServiceModeXi single‑character parameter.

   UOM. Defines the reading unit of measure (UOM). The UOM must match a UOM ID that is configured in IEE.

   Number of Dials. Defines the number of dials that are used for the meter read. Used to interpret the meter (start/end) read of the interval stream.

   Truncation Factor. Defines the number of decimals truncated when converting dial readings into engineering units. Default value is zero.

   Encoder Type. Defines the encoder type of the register. Limited to 10 characters.

   Display Multiplier. Defines the display multiplier of the meter (start/end) read of the interval stream. This value is used to calculate the meter multiplier (MM) with the following formula:

   CT * PT * DisplayMultiplier

   The MM is used to determine how to evaluate the start/end read. These 'register' reads are currently assumed to be raw, and the MM is applied only for evaluation for processes such as validation.

   Sequence. Defines the sequence of reading the register within the meter.
