Set PLC Date and Time dialog box
Setting and changing using program
1. The values written to the special data registers DT90054 to DT90057, which are allocated as the
clock/calendar setting area, are sent..
2. A value of H8000 is written to DT90058.
Note) The value can be sent using the differential instruction "DF", or by changing H8000 to H0000.
Do not always write H8000.
Example showing the date and time being written
Set the time to 12:00:00 on the 5th day when the X0 turns on.
Note:
No values have been set in the default settings, so the programming tool or another means must be
used to specify the values.
Example showing the clock/calendar being used
Sample program for fixed schedule and automatic start
In the example shown here, the clock/calendar function is used to output (Y0) signal for one second, at
8:30 a.m. every day.
Here, the "Hour/minute" data stored in the special data register DT90053 is used to output the signal at
the appointed time.
The hour data is stored in the upper 8 bits of DT90053 and the minute data in the lower 8 bits, in the
BCD format. This hour and minute data is compared with the appointed time (BCD), and the R900B
(=flag) special internal relay is used to detect whether or not it matches the appointed time.
30-second compensation
The compensation for 30 seconds is performed in the DT90058.
