1.1 Use

Before using the IR.LINK module (model: LQE546), make sure that the IR.Station module
(model: LQS021) is connected. The IR.LINK module communicates digital data and analog
data with the IR.Station module. When a remote I/O is used, it implements higher-speed
communication. It also supports a function that starts up a task upon the detection of a change in
digital input.
