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
