Devices, +3, +3, and +3 are not used for operation.
A clock data read by S(P).DATERD instruction can be directly subtracted.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.
Caution
(1) 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.
Program Example
(1) The following program subtracts the time data stored in the area starting from D10 from the clock data read from the

When the clock data is read by the S(P).DATERD instruction,
day of week is inserted between "second" and "millisecond".
If the S(P).DATE- instruction is used to read the clock data,
the data can be directly used for subtract
ion since it does not
perform the calculation for the day of the week.
