(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• The device other than the input (X) was specified at
• The device other than the output (Y) was specified at
Program Example
(1) The following program fetches, when X0 is turned ON, the 16 points 3 matrix starting from
X10, and stores the matrix into the area starting from M0.

Caution
(1) Note that the MTR instruction directly operates on actual input and output.
The output
MTR command turns OFF.
Turn OFF the specified output
(2) The MTR instruction execution interval must be longer than the total of response time of
input and output modules.
If the set interval is shorter than the value indicated above, an input cannot be read correctly.
If the scan time in a sequence program is short, select the constant scan and set the scan
time longer than the total of response time.
