APPLICATION-SPECIFIC FUNCTION: MODIF TIME PROG: (Modifying the parameters of a time programmer)

This function is used to display and/or modify the parameters of a TIME PROG function using a display function.

The digital type LINK TO TIME PROG input must be connected to the LINK TO MODIF TIME PROG output of the TIME PROG function for which the parameters are to be displayed or modified. This link is used by the compiler to determine to which function TIME PROG function a particular MODIF TIME PROG application-specific function is associated. If this input is connected to a digital output other than a LINK TO MODIF TIME PROG output of a TIME PROG function, or if it is not connected, a compilation error will be reported.

When the digital type EVENT READ input changes from OFF to ON, the information of the event whose number is specified on the INTEGER type EVENT NUMBER input is copied to seven INTEGER type outputs:

Digital type outputs associated with each of the preceding outputs can be used to check the validity of the information present on these outputs:

If a validity output is set to OFF, the value of the associated output is not valid and its value is indeterminate.

If the EVENT READ input is set to OFF, the validity outputs: YEAR VALID, MONTH VALID, DAY OF MONTH VALID, WEEKS VALID, DAYS OF THE WEEK VALID, HOUR VALID and MINUTE VALID are all set to OFF and the information present on the YEAR, MONTH, DAY OF MONTH, WEEKS, DAYS OF THE WEEK, HOUR and MINUTE outputs have no significance.

When the READ EVENT input is set to ON, the digital type WRITE EVENT input changing from ON to OFF will save the YEAR, MONTH, DAY OF MONTH, WEEKS, DAYS OF THE WEEK, HOUR and MINUTE values in the event whose number is specified on the EVENT NUMBER input.
