T310 Modbus -> HART - Fieldbus International AS

General description:

The T310 is a three-wire DIN rail module for interfacing Modbus transmitters to a HART network. The T310 is a complete transmitter module.The T310 generates a measured variable including astatus variable indicating the quality of the measurement. In addition to the Primary Variable (PV), the T310 may transfer three dynamic variables
from the Modbus instrument. A variety of data formats can be interfaced. The Primary Variable (PV) is continuously read and updated. T310 contains low-pass filtering functionality. The user can configure the damping value using a standard configuration tool.

The T310 communicates with an instrument through an  RS485 communication line. The protocol  between T310 and the instrument is the MODbus RTU protocol, but custom specific protocols may be accommodated.

The T310 supports the HART Universal Commands and the most used Common Practice command.

The Primary Variable (PV) is continuously read and updated.

The T310 supports the HART Universal Commands and the most used Common Practice commands.

The T310 contains an active current source. The module is powered from instrument power 24 V and also contains connections for power lines to the connected instrument.

There are terminals for connection of a handheld configurator.

The terminals are pluggable screw terminals.

Fint also provides gateways with tailored functionality.

Set-up of the T310 is done using a PC software tool, the SW002, purchased from Fint. Modbus address, register addresses, data types etc can be configured. Fint may preconfigure the T310 with the settings required for your specific Modbus instrument.

 

Applications:

The T310 is intended for integration of existing Modbus instruments into a HART network. It is intended for system integrators that are building HART based systems, and manufacturers of measuremt devices who want to offer HART capabilities in their Modbus instruments.
