tSH-700 Series Serial Port Sharer: Dual Master Control, Seamless Integration, and Simplified Deployment

The tSH-700 Series Serial Port Sharer enables two master controllers (e.g., PLCs) to simultaneously control the same set of serial devices. Installation is straightforward and requires no modifications to the original system settings, offering great flexibility and convenience for system expansion.

● Serial Port Sharing Mechanism

With three built-in serial ports, the tSH series allows two masters to simultaneously access or control multiple slave devices, enhancing operational flexibility and management efficiency. Whether for data acquisition or device control, synchronized operations are reliably supported.

● Modbus ID Filtering for Flexible Access Control

By combining "serial port sharing" with the "Modbus ID filtering" function, users can flexibly define access permissions for slave devices across different masters. For example, Devices 1 to 3 can be accessed exclusively by PLC#1, while Devices 4 and 5 can be shared by both PLC#1 and PLC#2. This ensures clear control allocation, prevents communication conflicts, and improves overall system stability and management efficiency.
