8 INSTRUCTIONS FOR DATA LINK
8.3 Refresh Device Write/Read Instructions
Operation error
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
Program example
• The following program writes 16 device values in B100 to the head of the refresh device (offset: 0) assigned for the remote
output (RY) in the remote I/O station on the station number 32 controlled by the CC-Link master station of the start I/O
number 0080H when X1C is turned on.
Precautions
• Do not execute the instruction in an interrupt program. If the instruction is executed, no processing is performed. In
addition, the completion device ((D1)+0), the completion device ((D1)+1), and SM739 do not turn on. If the instruction is
executed in a fixed scan execution type program, they also do not turn on.
• When the instruction is executed, do not rewrite the device data in (S2) until the completion device turns on.
