Communication
2.1 Overview
O/I Link Communication is a protocol for communication between Master and Slave, where a Touch connected to the
external device is configured as a Master and multiple Touch (Slaves) communicate with the external device via the

The Master Touch unit communicates with the external device by means of PLC Link Communication. The Master
Touch is called an O/I Link Master and a slave Touch connected to the O/I Link Master is called an O/I Link Slave. A
maximum of 15 O/I Link Slaves can be connected to an O/I Link Master.
