13.3.1 Operation and cautions for the MTR instruction
1. Command input
1) Setting the command input to normally Open
For the MTR instruction, set the command input to normally Open.
2. Input numbers used in the MTR instruction
1) Inputs available in MTR instruction
Use inputs X020 and later under normal conditions.
2) When using the inputs X000 to X017
*1
The receiving speed is higher. Because the output transistor recovery time is long and the input sensitivity is high,
however, erroneous input pulses may be counted.
To prevent erroneous input pulses, connect pull-up resistors (3.3 k
however, erroneous input pulses may be counted.
To prevent erroneous input pulses, connect pull-up resistors (3.3 k
Ω/0.5 W) to transistor outputs used in MTR
instruction.
For pull-up resistors, use the power supply shown in the table below.
For pull-up resistors, use the power supply shown in the table below.
The figure below shows an example of the FX

3. ON/OFF duration of input signals
Because 64 input points (8 rows
× 8 columns) are received in a cycle of 80 or 160 ms, the ON/OFF duration of each
input signal should be greater than or equal to the value shown below:
