9.1.2
Common-practice commands
9.1.3
Device specific commands
Command
Action
Meaning
38
Reset "Configuration changed" flag. Reset the "Configuration changed" response code, see
41
Perform device self test.
Initiates the self test function in the device (as during power
up); if no error occurs the response code "malfunction" (see
section 8.3.3) is cleared (if set).
42
Perform device reset.
Immediately after the response the microprocessor of the
device will be reset.
48
Read additional device status.
59
Write number of the response
preambles.
The number of preambles insert in response telegrams can
vary from 2 to 20. Default setting is 4.
106
Delete all delayed responses
pending for the host.
All pending response telegrams are deleted. Because only
one response buffer exists, the buffer is always deleted
(independent from the initiating host) in accordance with the
specification.
Command
Action
Meaning
128
Read parameterization of the
Multiplexer.
The actual parameterization is read out of the Multiplexer.
129
Read loop status.
With this command the status of the current loop can be read
out. The following information is supplied:
• Hardware fault
• Rebuild running for this loop
• SCAN activated for this loop
• Searching transmitter (due to "disappeared")
• Transmitter not responding ("disappeared")
• Transmitter responding again ("appeared")
• An other transmitter responded instead ("mismatched")
130
Read transmitter list (max. 49
entries, beginning with the given
index).
The long frame addresses of up to 49 transmitters are
returned beginning at the given index.
131
Read static data of up to 22
transmitters.
For the given long frame addresses the function returns the
following transmitter data:
• Current loop number (0 ... 15)
• Polling address
• Supported HART revision
• Minimum count of required preambles (5 ... 20)
132
Write static data of up to 22
transmitters.
Write static data (see 131). Values out of the range 5 ... 20
will be set to 5 or 20, respectively.
133
Remove transmitter from transmitter
list (max. 35 at the same time).
Transmitters with the given long frame addresses will be
removed from the transmitter list (and the SCAN list).
134
Read SCAN list (max. 49 entries,
beginning with the given index).
The long frame addresses of up to 49 transmitters are
returned beginning at the given index.
