Time (TIME)
The Time instruction can be used to set the time (24-hour
clock) in the CPU. The instruction requires two consecutive
V-memory locations (Vaaa) which are used to set the time. If
the values in the specified locations are not valid, the time will
not be set. The current time can be read from memory locations V7747 and V7766–V7770.
In the following example, when C0 is on, the constant value (K73000) 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 Time instruction uses the value in V2000 to set the time in the CPU.
