FEATURES
The HART 4 module can convert up to four analog devices into 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:
1)
A-HRT-4I
for HART input devices like process instruments.
2)
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.
The Hart 4 module is configured using the Aparian Slate application. This program can be
downloaded from
www.aparian.com
free of charge.
Hereafter the Hart 4 module will be referred to as the
module
