Cautions

1. Number of occupied devices

1) Eight input points are occupied from the input device number specified in

2) "n" output points are occupied from the output device number specified in

When specifying the output in

, make sure that "n" output numbers specified in

does not overlap the

output specified in

2. Limitation in the number of instructions

The MTR instruction can be used only once in a program.

3. Wiring

One diode of 0.1 A/50 V is required for each switch.

4. Output format

Use the transistor output format.

5. Cautions on writing during RUN

Even if an operand device is changed by write during RUN while the MTR instruction is executed, the PLC operates
using the device before change.
The changed device is reflected after the command input is set to OFF once and set to ON again.
