%IX0.0–
Turn on or off based on external
%IX511.15
input.
%QX0.0–
Turn on or off external outputs
%QX511.15
based on the operation result.
%MX0.0.0–
Used internally by the PLC
%MX0.886.15
program to store bit information.
%MX7.0.0–
Shared by multiple PLCs
%MX7.639.15
connected using PLC link.
%MX1.0–

%MX1.2999/
a TM instruction for the timer with
%MX2.3000–
the same number has reached 0.
%MX2.3071
%MX2.3000–
Turn on when the value set with
%MX2.3071/
a CT instruction for the counter
%MX1.0–
with the same number has
%MX1.2999
reached 0.
%MX11.0.0–
Turn on for one scan only. Used
%MX11.127.15
internally by the PLC program.
%MX10.0.0–
Turns on in the event of error.
%MX10.127.15
The error history is stored in
dedicated data registers.
%MX0.900.0–
Turn on or off based on specific
%MX0.910.15
conditions. Used internally as a
flag.
IEC
%IW0–

%QW0–
Code for specifying 16 external
%QW127
output points as one word (16
bits) of data.
%MW0.0–
Code for specifying 16 internal
%MW0.252
relays as one word (16 bits) of
data.
%MW7.0–
Code for specifying 16 link relays
%MW7.127
as one word (16 bits) of data.
%MW5.0–
Data memory used in a program.
%MW5.5999
Data is handled in 16-bit units
(one word).
%MW8.0–

%MW8.255
PLCs connected using PLC link.
Data is handled in 16-bit units
(one word)..
%MW3.0–
Data memory for storing the set
%MW3.1023
values of timers or counters. The
values are stored by
timer/counter number.
