Modbus TCP DAQ


LabJack produces low cost, high quality, data acquisition (DAQ) and control devices that are compatible with the Modbus TCP/UDP protocol. This means that they can be controlled by many industrial SCADA Systems/Modbus Client Applications, and used natively in any programming language that supports TCP connections. There are several Modbus TCP Libraries available in a variety of different languages.

Please note that the term "DAQ (data acquisition)" implies products that connect to a PC to acquire data. Hence, the term "Modbus TCP DAQ" means that this communication occurs using a PC's active network connection. If you need an instrument that can operate independently from a computer we have Data Logging compatible DAQ devices that are capable of periodically recording to internal memory for later use.
