Time is settable in seconds and may vary from a minimum of "0" to "60". When setting "0" seconds the retentive files of modified variables are all written one after theother without waiting. If a time of more than zero seconds is se, only one file will be written each time the interval time elaspes. This means, for example, that if the values of more than one variable changes at the same time, the last file will be updated after the time inserted in this property multiplied by the number of variables that changed value at the same time. For example, if setting the '1' second value in this property and 5 variables change at the same time, one file will be written every second therefore it will take 5 seconds to write all the retentive files (1 second x 5 variables).
When set with the "0" value, a variable change check for recording will be made every second and any changes made will be recorded straight away without delay.

Caution: this time is used for updating one single file. This means that if the value changes in more than one variable at the same time, the last file will be updated according to the value set in this property times the number of variables changed. Example, when setting a one second value in this property and five variables change at the same time, each file will be updated one second at a time, meaning that it will take about 5 seconds in all to update all five files (1 second per variable: 1 sec. x 5 variables = 5 secs).
