The HART-710 is a new HART Gateway to support Modbus and HART protocols. It allows the Modbus Master to access the HART Slave devices. These HART devices may be a transmitter, an actuator, a current output device and so forth. By using the HART-710, users can integrate their HART devices into Modbus network easily. Except for Modbus RTU protocol, the HART-710 also supports Modbus ASCII protocol. Therefore, HART-710 can be a powerful gateway to exchange the data between Modbus and HART network. Moreover, the HART-710 can be applied in the various hard environments by the high isolation protection design. And it is fit for the remote data acquisition, control, process automation, and factory automation, etc.
