CHAPTER 9 DEDICATED INSTRUCTIONS
A "dedicated instruction" is defined as an instruction designed to make programming easy for use of the intelligent
function module.
This chapter describes the dedicated functions available for the CC-Link IE Controller Network module.
9.1 List of Dedicated Instructions and Available Devices
(1) Dedicated instructions
Dedicated instructions can be used for transient transmission with a programmable controller on another station.
A station on the CC-Link IE Controller Network can access stations on other networks using link dedicated
instructions.
