The Maxiflex M1589D Dual Hart NIM is a Network
Interface Module that acts as a permanent host interface
device (primary master) on up to two Hart networks
simultaneously and is used to acquire data from the
HART loops and to make the data available for SCADA,
data-logging etc. using the Maxiflex system.
The Hart NIM plugs into an I/O slot on a Maxiflex base
and independently interrogates field devices on two Hart
networks, making the data available to the Maxiflex
system.
This data may be accessed by the entire range of
Maxiflex CPU's. The NIM is designed to be self
configuring for ease of use. Once powered up, the NIM
searches for HART devices on each of its two HART

interfaces and builds an inventory of devices found.
Various data elements are continuously and
automatically read from the device and stored in the
Data Interchange Table (DIT) in the device for access by
the rest of the Maxiflex system.
The HART NIM handles all HART communications and
exchanges data with the system by means of a 3000
register Data Interchange Table (DIT).
All system configuration data and dynamic data can be
read and written through this convenient table interface.
This data is then accessible by the CPU, SCADA, DCS
or PLC systems as regular data registers in the system.
The link to the HART device is made transparent to the
rest of the system.
