I-7567

The I-7567 is a USB to HART converter designed for the master device of HART protocol. It allows users to access the HART slave by using virtual COM-port. It can be used with HART slave devices like transmitters, actuators, current output devices, etc. It also comes with free utility tool for configuration.

The HART (Highway Addressable Remote Transducer) protocol uses the Bell 202 Frequency Shift Keying (FSK) standard to superimpose digital communication signals on the 4-20 mA loop current shown as below figure. HART communicates at 1200 bps without interrupting and interference with the 4-20mA signal and allows a host application (master) to send/receive digital information from a smart field device. The 4-20mA signal communicates the primary measured value - the fastest and most reliable industry standard. The digital signal can be used for additional device information including device status, diagnostics, additional measured or calculated values, etc. Therefore, the HART communication including analog and digital information provides a low-cost and very robust complete field communication solution that is easy to use and configure. HART is a master/slave protocol which provides for up to two masters (primary and secondary) and the secondary master such as handheld can be used to monitor/control the informatoin of HART bus. HART can be used in various modes such as point-to-point or multi-drop for communicating information to/from smart field instruments and central control or monitoring systems. The following are the description of two main HART operation modes.

• Relatively easy to understand and use, the HART protocol provides access to the wealth of additional information (variables, diagnostics, calibration, etc.)
• HART is a no risk solution for enhanced field communication
• Compatibility with standard 4-20mA wiring
• Simultaneous transmission of digital data
• Risk reduction through a highly accurate and robust protocol
• Increase Plant Availability
• Reduce Maintenance Costs
• Improve regulatory compliance
