Mitsubishi Electric MELSEC iQ-R Series Programming Manual page 1028

Processing details
• These instructions read "year, month, day, hour, minute, second, day of week, and millisecond" from the clock element of
the CPU module, and store the read data in binary in the device specified by (d) and later.
(Data) (d)
(Clock Year
element)
(Setting range) 1980 to 2079
• "Year" stored in the device specified by (d) is a 4-digit year.
• "Day of week" stored in the device specified by (d)+6 is a number from 0 to 6 corresponding to Sunday to Saturday.
Day of week
Stored data
• Data is automatically corrected in leap years.
Precautions
• These instructions read clock data and store it in the device even when incorrect click data is set in the CPU module.
(Example: February 30) When setting clock data with the DATEWR(P) instruction or engineering tool, be careful not to set
incorrect clock data.
• When millisecond clock data is read, the maximum error is 2ms. (This error means the difference between the data stored
in clock elements in the CPU module and the data read by the S(P).DATERD instruction.)
Operation error
There is no operation error.
