Precautions
• If link direct access was performed from the CPU module and Motion module built-in program at the same time, the
processing may not be performed correctly. When performing link direct access with the CPU module and Motion module
built-in program, adjust the access timings to prevent overlap. Or, configure them so that they do not access the same area
(units of 32 points for bit data/units of 2 points for word data).

SET J1\Y101
RY100 := TRUE;
• Even if direct access is made on a link device to which station assignment was not performed in "Network Configuration
Settings" under "Basic Settings", data can be read or written without any error.
• When conducting a link direct access to a motion control station link device, the next operation will occur. The values
written to RX/RWr assigned to the motion control station are not reflected in the output to the motion control. Additionally,
the values written to the motion control station RX/RWr are not stored in the local station link device (RX/RWr). When
reading RX/RWr assigned to the motion control station, the value written last (initial value 0) by link device direct access,
etc. of the link device is read.
