Data Logger Recording Time Properties

The Data Logger's Recording Time properties allow you to define the time frequencies and timeframes with which the data recordings are to be executed when the "Record on Time" option has been selected in the Data Logger's Style property group.

To change the Data Logger's Recording Time properties, select the object and use the Movicon 'Properties Window' that appears.

 

 

Hour Frequence

This value represents the Data Logger's sampling time in hours. This value is only used when the  "Record on Time"  property has been enabled.

 

Minutes Frequence

This value represents the Data Logger's sampling time in minutes. This value is only used when the  "Record on Time"  property has been enabled.

 

Seconds Frequence

This value represents the Data Logger's sampling time in seconds. This value is only used when the  "Record on Time"  property has been enabled.

 

MilliSeconds Frequence

This value represents the Data Logger's sampling time in milliseconds. This value is only used when the "Record on Time"  property has been enabled.

 

Enable Day Timeframe

This setting allows you to enable a day timeframe for the data recording. When you activate this function, you will need to specify within which timeframe the data recording is to be executed during (unless this is determined by the "Recording Variable"). All the Data Logger recording commands executed outside the established timeframe will be ignored except for the recording executed with the "Record on Command" variable which remains active.

 

The recording of data within the set timeframe, especially if they are variables, can also be executed by using the "Recording Variable".

 

Timeframe from

This is used to set which time the Datalogger is to start recording data when the 'Enable Day Timeframe' has been enabled.

 

Timeframe to

This is used to set which time the Datalogger is to finish recording data when the 'Enable Day Timeframe' has been enabled.

 

Tot. Nr. Records

The number entered here is calculated based on the modality described in topic on  "Historicals Management"

 

Data Max.Age

This field defines how long the data is to be stored before being recycled. You should take into account the frequency with which data recordings will be executed when entering a time here to avoid floading tables with too much data. Basically, the more frequent data recordings are executed, the more the maximum recording time will have to be reduced for each Data Logger.

For further information please refer to the paragraph on  "Archive Sizes".

 

The maximum recording time you should enter here should be based on your needs.  You should also take into account both the recording frequency and the type of database you will be using. For instance, if you use a Access2000 database, you will be limited in the number of data recordings that can be executed compared to that of a SQL Server database.
