7 APPLICATION INSTRUCTIONS
7.18 Matrix Input Instruction
901
7
• This instruction sequentially reads the input of 16 pointsn 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.
■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
[Operation]
• 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.
• 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.
