Communication
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.
2.2 O/I Link Communication Settings
These settings are configured under the O/I Link tab on the Project Settings dialog box. The Project Settings dialog
box can also be accessed using the following methods.
•Click Project on the Configuration tab.
•Double click Project Settings in the Project window.
The O/I Link Communication Settings can only be configured when O/I Link Master or O/I Link Slave is selected
in Function under Interface Settings on the Communication Interface tab. For details, refer to Chapter 4 “3.5
O/I Link Tab” on page 4-53.
