Functional Specifications
The MVI56-HART module supports the HART Multidrop
implementation of the protocol. Following are some
general specifications for the module:
? Built in accordance to the HART Bell 202 Frequency
Shift Keying (FSK) standard to superimpose digital
signals at a low level on top of the 4 – 20mA
o Four independent HART master ports that are
completely user-configurable
o Supports up to 15 devices per port
o Point-to-point (slave address 0) or Multidrop
(slave address 1 to 15) modes supported
? Supports 99 universal and common practice
commands per port to control and monitor devices
with integer, IEEE754 floating-point and packed
ASCII character string data blocks
? Burst mode can be used for faster update of data
from a single slave? Supports an auto polling feature that will
automatically collect data from each HART
instrument on the channel and store the data in the
module database
? Communication ports can be configured as a
secondary master (that is, handheld configuration
device)
Protocol Supported: HART protocol uses the Bell 202
standard frequency shift-keying (FSK) digital signal to
communicate at 1200 baud, superimposed at a low level
on the 4 to 20mA analog measurement signal.
