Clock/Calendar Instructions

Date (DATE)
The Date instruction can be used to set the date in the CPU.
230
The instruction requires two consecutive V-memory locations
240 (Vaaa) to set the date. If the values in the specified locations are
not valid, the date will not be set. The current date can be read
250-1
from 4 consecutive V-memory locations (V7771–V7774).

In the following example, when C0 is on, the constant value (K94010301) is loaded into the
accumulator using the Load Double instruction (C0 should be a contact from a one shot
(PD) instruction). The value in the accumulator is output to V2000 using the Out Double
instruction. The Date instruction uses the value in V2000 to set the date in the CPU.
