Rules for Using Time Profiles for Control Profiles with WITS Database Points

You can configure a WITS analog, counter or binary point so that it is in a specific state at a specific time. To do this, you use Time Profiles. There are some rules that you need to follow when using Time Profiles with WITS. The rules differ, depending on the type of WITS database point.

 

For analog points:

• The Time Profile has to be a Float type of Time Profile.
• The Time Profile Mode has to be set to Stepped or Interpolated. This will depend on the value in the Interpolation field on the Analog Point tab. If the value in the field is 0, then the Mode will be Stepped, otherwise it will be Interpolated.
• The Time Profile has to have its Time Zone set to UTC.
• The Maximum Vectors Per Day has to be set so that it is equal to, or lower than the maximum number of vectors per day specified in the Field Device's Device Profile (see Display a WITS Device Profile).
• The minimum number of vectors per day is 1.
• The first vector for each day has to be at midnight (as specified by the WITS-DNP3 standard).
• The range of the Time Profile has to be within the Zero Scale and Full Scale of the points that will use the Time Profile (see Alarm Limits for WITS Analog Points).
  

 

For counter points:

• The Time Profile has to be a Double type of Time Profile (as Geo SCADA Expert scales counter points).
• The Time Profile Mode has to be set to Stepped or Interpolated. This will depend on the value in the Interpolation field on the Counter Point tab. If the value in the field is 0, then the Mode will be Stepped, otherwise it will be Interpolated.
• The Time Profile has to have its Time Zone set to UTC.
• The Maximum Vectors Per Day has to be set so that it is equal to, or lower than the maximum number of vectors per day specified in the Field Device's Device Profile (see Display a WITS Device Profile).
• The minimum number of vectors per day is 1.
• The first vector for each day has to be at midnight (as specified by the WITS-DNP3 standard).
• The range of the Time Profile has to be between 0 and (2³² - 1) × Multiplier for the points that will use the Time Profile. (For more details on the Multiplier setting, see Configure the Multiplier Value .

 

For binary points:

• The Time Profile has to be an Unsigned Long type of Time Profile.
• The Time Profile Mode has to be set to Stepped and the Time Zone set to UTC.
• The Maximum Vectors Per Day has to be set so that it is equal to, or lower than the maximum number of vectors per day specified in the Field Device's Device Profile (see Display a WITS Device Profile).
• The minimum number of vectors per day is 1.
• The first vector for each day has to be at midnight (as specified by the WITS-DNP3 standard).
• The range of the Time Profile has to be between 0 and 1 if the binary point is single bit, or 0 to 3 if the binary point is double bit.
