2. Changeover of the year display (to the four-digit mode)
When changing the year data to the four-digit mode, add the following program.
D8018 is set to the four-digit year mode on the second ladder scan in RUN mode.
1) The PLC is usually operating in the two-digit year mode.
When the above instruction is executed during RUN and "K2000 (fixed value)" is transferred to D8018
(year data), D8018 switches to the four-digit year mode.
2) Execute this program every time the PLC enters RUN.
Only the year data display switches to four-digit mode when "K2000" is transferred. The actual time date
is not affected.
3) In the four-digit year mode, the values "80" to "99" correspond to "1980" to "1999" and "00" to "79"
correspond to "2000" to "2079".
Examples: 80 = 1980, 99 = 1999, 00 = 2000, 79 = 2079
4) When connecting the data access unit FX-10DU-E/20DU-E/25DU-E, use the two-digit year mode.
If the four-digit year mode is selected, the year data will not be displayed correctly.
Note that the clock is changed to the 2-digit year mode when the clock is set from the FX-10DU-E/20DU-
E/25DU-E while the PLC is operating in the 4-digit year mode.
