Additional remarks, below.
7. In general, the conditional contact used in the instruction is SM400: the flag is always ON when CPU runs.
8. The value in n must be between 2–8.
Example 1
1. When M0 is ON, the MTR instruction is executed. The instruction reads the states of the two rows of switches in
order, and stores them in the internal relays M10–M17 and M20–M27 respectively.
2. The diagram below is the external wiring diagram of the 2-by-8 matrix input circuit for X0.0–X0.7 and Y0.0–Y0.1.
The corresponding internal relays of the 16 switches are M10–M17 and M20–M27.
3. The instruction connects eight input devices starting from X0.0 to the two output devices starting from Y0.0 to form
the two rows of switches. The matrix scan reads the states of the two rows of switches, and stores the states in the
devices starting from M10 (specified by D
and stores the states of the second row of switches in M20–M27.
