15.1 Link Dedicated Instructions
*2 For the specifications of the string data to be specified, refer to the following.
 Page 1452 Specifications of character string data specified by link dedicated instructions
■ Applicable devices
*1 FX and FY cannot be used.
*2 FD cannot be used.
*3 T, ST, C, and FD cannot be used.
• The SWRITE instruction cannot be executed when the target station is ACPU.
• Specify the target station start device (d1), to which data is to be written, by considering the range in which
the data that has been written can be stored.
(Example: When areas D150 and after in the target station CPU module are already in use)
• When the target station for which the SWRITE instruction is executed is the basic model QCPU, the write
notification device for the target station specified by argument (d3) is ignored. The operations of the
SWRITE instruction are the same as those of the WRITE instruction.
• The SWRITE instruction can be programmed by omitting argument (d3). However, the operations are the
same as those of the WRITE instruction. The operations of the SWRITE instruction can be selected
according to whether (d3) is omitted or not.
