The HART 4 module can convert up to four analog devices into: EtherNet/IP, Modbus-TCP, or DNP3 TCP/UDP. This includes input and output HART and non-HART analog devices.
- HART to EtherNet/IP
- Analog Input or Output (4 Channels)
- DNP3 with Secure Authentication
- Burst Mode
- HART Data & Diagnostics
- Onboard 1000 point trend
- DTM Available
The HART 4 module can convert up to four analog devices int either EtherNet/IP, Modbus-TCP, or DNP3 TCP/UDP protocols. This includes 4 to 20 mA input and output devices with or without HART communications as well as 0 to 20 ma devices without HART.
The Hart 4 is available in Input or Output variations:
- A-HRT-4I for HART input devices like process instruments.
- A-HRT-4O for HART output devices like valve positioners.
The conversion to EtherNet/IP enables a HART device to be added directly into a Rockwell Automation Logix IO tree. The Modbus-TCP option enables a HART field device to be viewed as a Modbus Slave. The DNP3 option converts a HART field device into a DNP3 Outstation. The DNP3 option, also supports Secure Authentication, ensuring secure communications across the Ethernet network.
In addition, a rich collection of process and diagnostic information is provided directly into Logix, without the use of any explicit messaging. HART commands can also be relayed to the device using an EtherNet/IP message relay object. A DTM (Device Type Manager) is available further simplifying device configuration and management using an FDT frame. A built-in webserver provides detailed diagnostics of system configuration and operation as well as field device specific diagnostics.
