2.3.3 HART Command List
The HART Command List specifies the commands to be executed to the HART
devices connected to a channel. A HART command can be seen as an outgoing
message to the HART devices that provides Write Data for a specific command
or a response message that carries process data (Read Data) back to the
module. The ProLinx module supports three kinds of data blocks in the Universal
and Common Practice commands. These data blocks are:
Integers
IEEE 754 Floating Point Numbers (32 bits)
Packed ASCII character strings
The Packed ASCII character strings are unpacked and placed with the integers
data block.
For all commands, it is possible to select where the Write Data comes from; it
can be in the module’s internal database or it can be configured as a fixed data
block in the command.
For response messages from HART devices, it is possible to configure where the
Floating Point Data and Integer Data will be placed in the module’s internal
database, but this is only possible for the Universal and Common Practice
commands. In the case of Device Specific commands, all the Read Data is
placed in the Integer data section. See HART Command Support for a listing of
supported HART commands.
