This section explains the settings in the Advanced Settings dialog box.

 

For items not listed here, please refer to "Demand Monitoring" in the Screen Library Reference.

 

■ Demand name/comment

 

p_demand_0042

 

item

explanation

name

Specify the name of the demand monitor. The name specified here will be displayed in the selection combo box on the demand monitor screen.

 

p_demand_0043

 

comment

 

You can specify any comment.

 

 

 

 

■ Demand tag/counter minimum value/counter boundary value

 

p_demand_0044

 

item

explanation

Demand Tags

 

Set the tag path of the tag to be monitored (the tag of the power metering ring counter).

Counter Minimum Value

 

Sets the minimum ring counter value for the demand tag.

If the counter is between 0 and 99999, it will be set to "0".

Counter Boundary Value

 

Sets the boundary value for the demand tag's ring counter value.

Set the boundary value to the maximum counter value + the counter increment unit.

For example, if the counter ranges from 0 to 99999 and counts up by one, enter "100000."

If the counter increment is a decimal, for example if the maximum counter value is 999.9 and the counter increment is 0.1, specify "1000".

 

 

 

 

■ Conversion value/cycle time/unit

 

p_demand_0045

 

item

explanation

Conversion Value

 

The conversion value is a parameter used to calculate the demand power from the amount of power consumed over a 30-minute period.

In most cases, set this to "2".

 

For details on setting the conversion value, see "About weighing counter weights and conversion value settings".

 

Cycle Time

 

When monitoring power demand, the general demand time limit is 30 minutes, so in most cases you should set it to "30".

unit

 

For power demand, you will most likely specify "kW."

 

 

■ Cycle type

 

p_demand_0046

 

For the cycle type setting, select either "AUTO" or "MANUAL".

 

For standard projects, "MANUAL" is set.

 

Please be careful when setting the cycle type. For details, please refer to "Demand cycle reset process".

 

 

 

■ Contract demand/Target demand/Display maximum demand

 

p_demand_0047

 

item

explanation

Contract Demand

 

Enter the setting value for the "contract demand line" to be displayed on the demand graph.

This setting value is the setting value for the position of the line displayed on the graph as a guideline and is unrelated to alarm detection.

Target Demand

 

Enter the setting value for the "target demand line" to be displayed on the demand graph.

This setting value is also the setting value for the position of the line displayed on the graph as a guideline and is unrelated to alarm detection.

Display Maximum Demand

 

Sets the maximum width of the Y-axis of the demand graph.

 

 

■ Forecast value calculation method/moving average count/forecast start time/forecast calculation period

 

p_demand_0048

 

The forecast calculation method allows you to select from the following three methods for calculating the slope of the forecast line.

 

•TWOPOINTS - Two-point calculation method

•MOVING_AVERAGE　・・・Moving average method

•LEAST_SQUARES_METHOD: Least squares method

 

These parameters are used to calculate the demand forecast. For details on how the forecast is calculated, please refer to "Demand forecast calculation method".

 

The forecast start time is the time from the start of the demand cycle until the forecast line is displayed. The forecast line will not be drawn until the time (minutes) specified here has elapsed.

 

 

 

■ Current value output tag / Reset output tag / Predicted value output tag

 

p_demand_0049

 

The current demand value, forecast value, and reset status can be written to tags.

 

For information on writing demand monitoring information to tags, please refer to the description in "About tag output of demand monitoring information".

■Alarm output tag

 

The demand alarm detection status can be written to a tag. If you are using Alarm server alarm monitoring, specify the destination tag with this parameter and register it in the alarm master.

 

For information on writing demand monitoring information to tags, please refer to the description in "About tag output of demand monitoring information".

 

 

■ Level type

 

Double-clicking the target cell will display the alert level type selection dialog.

 

p_demand_0057

item

explanation

Ratio Type

 

"Ratio type" specifies the alarm power setting as a ratio to the target demand. For example, if the target demand is "1800" and the alarm power is specified as "0.9", the alarm threshold will be monitored internally as 1620.

Raw Value Types

 

"Raw value type" specifies the alarm power setting by value. If you specify "1500" as the alarm power, an alarm will occur if the demand forecast exceeds 1500.

 

 

 

■ Alarm power

 

Set the demand alarm threshold value. Set the content according to the setting selected in Level Type.
