tSH-700 Series

The ICP DAS tSH-700 module is a serial port sharer that provides a number of functions, including “Baud Rate Conversion”, “Modbus RTU/ASCII Conversion” and “Two Masters Share One Slave”. The built-in web server provides easy configuration interface, and no console commands are required.

The Baud Rate conversion function allows a single master device to communicate with slave devices using different baud rates and data formats. Most query-response protocols (half-duplex), e.g. DCON, are supported in the raw data mode. Full-duplex communication should also work when the data size is smaller than the built-in 512 bytes buffer on each serial port.

The Modbus RTU/ASCII conversion function allows a single Modbus RTU/ASCII master device to communicate with Modbus RTU/ASCII slave devices using different protocols, baud rates and data formats.

The built-in read-cache function is used to store previous requests and responses of the Modbus messages in the memory buffer of the tSH-700 module. When other HMI/SCADA master controllers requiring the ame information from the same salve RTU device, the cached response is returned immediately. This feature dramatically reduces the loading on the slave serial port communication, ensures faster responses to the master, and improves the stability of the entire system.
