Tool It indicates the area that can be set using the tool software.
 Reading from unit memories (UM)
It is possible to read the areas which are shown with "Available" in the "R" column in the
following table using transfer instructions or arithmetic instructions with user programs. The
operand of an instruction is specified by the combination of the slot number where the slot is
installed and a unit memory number (UM).
Example) Program to read the elapsed value area (UM00110) of the counter CH0 of the multi
I/O unit installed in the slot number 1 (S1) to an arbitrary data register (DT100)

 Writing to unit memories (UM)
• When the mode changes from PROG. to RUN, the configuration information set by the tool
software will be stored.
• It is possible to write to the areas which are shown with "Available" in the "W" column in the
following table using transfer instructions or arithmetic instructions with user programs. The
