Caution
(1) This instruction reads clock data and stores those to a specified device even if a wrong clock data is set to the CPU
module. (example: Feb. 30th)
When setting clock data with the DATEWR instruction or GX Developer, make sure to set a correct data.
(2) Time error of reading a clock data of millisecond is a maximum of 2ms. (Difference between the data memorized by clock
element inside of the CPU module and the data read by this function.)
(3) Specifying digit for the bit device can be used only when the following conditions (a) and (b) are met.
(a) Digit specification: K4
(b) Head of device: multiple of 16
When the above conditions (a) and (b) are not met, INSTRCT CODE ERR.
(error code: 4004) will occur.
