Processing details
• This instruction sequentially reads the input of 16 pointsn columns connected to the (s) specified input number and after,
and stores the input data that has been read in the device specified by (d2) and later.
• One scan reads one column (16 points) of data.
• The instruction sequentially repeats the reading of data from column 1 to column (n).
• In the device specified by (d2) and later, the data in column 1 is stored in the 16 points from the start and the data in column
2 is stored in the next 16 points. For this reason, the MTR instruction occupies 16(n) points from the device specified by
(d2).
• (d1) is the output for selecting the column to be read and is turned on and off automatically by the system. The (n) points
from the device specified by (d1) is used.
• Only a device number which is a multiple of 16 can be specified in (s), (d1), and (d2).
• A value from 2 to 8 can be specified in (n).
• No processing is performed in the following cases.
• The device number specified by (s), (d1), or (d2) is not a multiple of 16.
• The device specified by (s) is outside the range of actual inputs.
• The device specified by (d1) is outside the range of actual outputs.
• In the device specified by (d2) and later, 16(n) points of data is outside the range of the relevant device.
• (n) is outside the range from 2 to 8.
■Program example
A program that reads the matrix data(16 points  three columns) connected to X10 and later, and stores the read data to M0
and later when X0 turns on
X0
[Operation]
• When Y20 turns on, the instruction reads the input signals of the 1st column, and stores the read data to M0 to M15.
• When Y21 turns on, the instruction reads the input signals of the 2nd column, and stores the read data to M16 to M31.
• When Y22 turns on, the instruction reads the input signals of the 3rd column, and stores the read data to M32 to M47.
