Matrix input
MTR
• This instruction reads the input from 16 points n-rows starting from the input number designated by (S), then stores
fetched input data to area starting from the device designated by (D2).
• One row (16 points) can be fetched in 1 scan.
• Fetching from the first to the n th row is repeated.
• The first through the 16th points store the first row of data and the next 16 points store the second row of data at the
devices following the device designated by (D2). For this reason, the space of 16 n points from the device designated by
(D2) are occupied by the MTR instruction.
• (D1) is the output needed to select the row which will be fetched, and the system automatically turns it ON and OFF. It uses
the n points from the device designated by (D1).
• Only device numbers divisible by 16 can be designated for (S), (D1) and (D2).
• For n, a value in the range from 2 to 8 can be assigned.
• No processing is performed in the following cases.
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
(S): Head input device (bits)
(D1): Head output device (bits)
(D2): Head number of the devices where matrix input data will be stored (bits)
n: Number of input rows (BIN 16 bit)

• The device number designated by (S), (D1), or (D2) is not divisible by 16.
• The device designated by (S) is outside the actual input range.
• The device designated by (D1) is outside the actual output range.
• The space 16 n points following the device designated by (D2) exceeds the relevant device range.
• The value for n is not between 2 and 8.
