Clock/Calendar Instructions

Date (DATE)

The Date instruction can be used to set the date in the
Memory Cartridge. The instruction requires two consecutive
V-memory locations (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 from four consecutive V-memory
locations (V7771–V7774).
Year

Day of Month
Day of Week
The values entered for the day of week are:
0=Sunday, 1=Monday, 2=Tuesday, 3=Wednesday, 4=Thursday, 5=Friday, 6=Saturday
Operand Data Type
V-memory
In the following example, when C0 is on, the constant value (K00010301) is loaded into the
accumulator using the Load Double instruction (C0 can 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. The
example loads the date January 3, 2000.
