Data memory for storing settings
and error codes.
Index registers 1 DI0 %MD6.0 Data memory used to modify
constants and memory area
addresses.
1)
There are two memory types, the hold type that saves the conditions that exist just before turning the power
off or changing from RUN to PROG mode, and the non−hold type that resets them. FP0 T32C: The hold and
non−hold type memory areas can be changed by setting the system registers. All other CPU types: The hold
and non-hold type memory area is fixed and allotted the numbers as shown below.
2)
The number of points for timer and counter relays can be changed using system register 5. The numbers in
the table are the default settings.
