2.1 Overview
O/I Link Communication is a protocol for communication between Master and Slave, where a MICRO/I connected to
the external device is configured as a Master and multiple MICRO/I (Slaves) communicate with the external device via
the Master.
The Master MICRO/I unit communicates with the external device by means of Device Link Communication. The
Master MICRO/I is called an O/I Link Master and a slave MICRO/I 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.
