Turn on or off based on external
%IX12.15
input.
%QX0.0–
Turn on or off external outputs
%QX12.15
based on the operation result.
%MX0.0.0–
Used internally by the PLC
%MX0.62.15
program to store bit information.
%MX1.0–
Turn on when the value set with
%MX1.99/
a TM instruction for the timer with
%MX2.100–
the same number has reached 0.
%MX2.143
%MX2.100–
Turn on when the value set with
%MX2.143/
a CT instruction for the counter
%MX1.0–
with the same number has
%MX1.99
reached 0.
%MX0.900.0–
Turn on or off based on specific
%MX0.903.15

flag.
IEC
%IW0–
Code for specifying 16 external
%IW12
input points as one word (16 bits)
of data.
%QW0–
Code for specifying 16 external
%QW12
output points as one word (16
