Setting the timer setting value from the setting and display unit
The timer T setting value can be set with the following two methods.
 Method to validate the setting value (Kn) programmed with the sequence program (Fixed timer)
 Method to validate the setting value set from the setting and display unit (Variable timer)
(Note that even when this method is used, the setting value (Kn) must be programmed in the sequence program. In this case,
the Kn value will be ignored during the operation. When a data register D is used for the setting value, the contents of the data
register D will be the setting value regardless of the parameter.)
 Methods for setting the number of fixed timer and variable timer points
The number of points of the fixed timer and variable timer in all of the timer T points can be set with the bit selection
parameter. This setting is enabled when the PLC is restarted.

 Variable timer validity setting bit on program side
A bit selection and display unit and validate the setting values in the sequence program. This setting is enabled when the PLC
is restarted. (This bit is valid also for the integrated timer.)
