Flags
Note In CS1-H, CJ1-H, CJ1M, and CS1D (for Single-CPU System) CPU Units,
these Flags are left unchanged.
In CS1 and CJ1 CPU Units, these Flags are turned OFF.
Precautions MOVR(560) cannot set the PLC memory addresses of timer/counter PVs.
Use MOVRW(561) to set the PLC memory addresses of timer/counter PVs.
The contents of an index register in an interrupt task is not predictable until it
is set. Be sure to set a register using MOVR(560) in an interrupt task before
using the register.
Any changes to the contents of an IR or DR made in an interrupt task will not
affect the contents of the register in a cyclic task.
Example When CIO 000000 is ON in the following example, MOVR(560) writes the
PLC memory address of CIO 0020 to IR0.
3-8-15 MOVE TIMER/COUNTER PV TO REGISTER: MOVRW(561)
Purpose Sets the PLC memory address of the specified timer or counter’s PV in the
specified Index Register. (Use MOVR(560) to set the PLC memory address of
a word, bit, or timer/counter Completion Flag in an Index Register.)
