Overview
HLS (Hi-speed Link System) is a high-speed field network with a 1-master:multiple-slave configuration.
It can connect up to 63 slave ICs and supports I/O control of up to 2,016 points (1,008 inputs + 1,008 outputs). The communication protocol is built into the IC.
The CPU can control numerous I/O operations simply by reading and writing to memory.
Features
• Ultra-high-speed control (up to 15 μs per node)
- Up to 63 nodes can be connected.
RS485-based multidrop communication
- Simple I/O control with reduced CPU load
- Analog control is also supported (when using units from partner manufacturers).
- Equipped with error detection and notification functions.

response speed
In full-duplex communication mode, the following response speeds are achieved even with a maximum of 63 nodes connected.
12Mbps: 955.5μs
6Mbps: 1911μs
3Mbps: 3822μs
In half-duplex communication, the signal strength is approximately doubled.
Control method
The master IC contains the I/O registers for each slave.
- Input acquisition (Read): The CPU simply reads the memory of the master IC.
- Output control (Write): The CPU simply writes to the master IC's memory.
This allows you to control the I/O of each slave. Communication processing is automatically handled by HLS.
Error monitoring function
When a communication error occurs, you can check the following in the registers:
Additionally, the CHK1/CHK2 pins support LED display and interrupt notification.
