APPLICATION-SPECIFIC FUNCTION: ARCHIVE S (SAVING AND TIME STAMPING OF A VALUE)

This function is used to save the integer value present on the INTEGER type VALUE input on a change from OFF to ON of the digital ARCHIVE input if the RESET TO ZERO input is OFF.

When this value is saved, the function also saves the current time and date, which will then be available as six INTEGER type outputs:

If the ARCHIVE input is activated several times, only the data relating to the last activation is saved.

The digital ARCHIVE VALID output changes to ON to indicate the validity of the current save.

Setting the digital RESET TO ZERO input to ON forces the ARCHIVE VALID output to OFF. The values of the other outputs are then to be considered as indeterminate.

The Parameters tab contains a check box which reinitialises the function in the event of a controller power break.

If it is not connected, the ARCHIVE input is fixed at OFF.

If it is not connected, the VALUE input is fixed at 0.

If it is not connected, the RESET TO ZERO input is fixed at OFF.

Caution: DISPLAY functions can be connected on the outputs of this function. The DISPLAY function can be used to modify the value displayed if the Modification authorised parameter is checked. If the user uses this option, it is at his own risk, because the archiving outputs, which are validated by ARCHIVE VALID, represent a coherent state: "VALUE - DATE" may be rendered nonsensical by an arbitrary and partial modification by a DISPLAY modifier.
