6.3 HMI Link Register (LLR) Assignment
This section describes how to allocate and the operation of HMI Link Registers (LLR) in Sub Host Communication.
●
Example of HMI Link Register (LLR) Settings
Use the Device Link Communication between the external device and the MICRO/I's serial interface (COM1), and use
the Sub Host communication between the external device and the MICRO/I's serial interface (COM2).
Allocate the following external device addresses to the HMI Link Registers (LLR).
■
Settings in the Communication Interface tab on the Project Settings dialog box

Don't use the frequent write operation for HMI Link Register (LLR) which is caused by a script and a word
command. It may make the reading data operation too much slow.
