Appendix Programming Information
Type
Index registers
There are two memory types, the hold type that saves the conditions that exist just before turning the power
1)
off or changing from RUN to PROG mode, and the non−hold type that resets them. The hold and non−hold
type memory areas can be changed by setting the system registers.
The number of points for timer and counter relays can be changed using system register 5. The numbers in
2)
the table are the default settings.

IEC
%MD6.0– Data memory used to modify
%MD6.13 constants and memory area
addresses.
IEC
%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– Turn on when the value set with
%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– Code for specifying 16 external
%IW127 input points as one word (16 bits)
of data.
%QW0– Code for specifying 16 external
%QW127 output points as one word (16
bits) of data.
