Precautions
Using CPS(114) Results in the Program
Do not program another instruction between CPS(114) and the instruction
controlled by the Arithmetic Flag because the other instruction might change
the status of the Arithmetic Flag. In this case, the results of instruction B might
change the results of CPS(114).
The immediate-refreshing variation (!CPS(114)) can be used with words allo-
cated to external inputs specified in S
cuted, input refreshing will be performed for the external input word specified
in S and/or S
1 2
refreshing cannot be performed on inputs allocated to Group-2 High-density
I/O Units or Units mounted to Slave Racks.)

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.
Do not program another instruction between CPS(114) and an input condition
that accesses the result of CPS(114) because the other instruction might
change the status of the Arithmetic Flags.
