The Maxiflex M1438A 8H is an Input Module that acts as
a permanent host interface device (primary master) on
up to eight 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 M1438A plugs into an I/O slot on a Maxiflex base
and independently interrogates field devices on eight
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 eight 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 M1438A handles all HART communications and
exchanges data with the system by means of a 8000
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.
