Communication
6.1 Overview
Sub Host Communication is a function for communicating with an external device using the MICRO/I's HMI Link
Registers (LLR).
The external device addresses are allocated to HMI Link Registers (LLR). When MICRO/I receives a request to read
from or write to HMI Link Registers (LLR), it reads from or writes to the allocated external device addresses, and the
execution results are stored in HMI Link Registers (LLR).
6.2 Supported Protocols and Communication Driver
The Sub Host communication can be used with the following protocols and communication drivers:
