9.1.3 Device specific commands
Command Action
Read parameterization of the
128

Multiplexer.
Read loop status.
129

Read transmitter list (max. 49
130 entries, beginning with the given

index).
Read static data of up to 22
transmitters.

transmitters.

list (max. 35 at the same time).
Read SCAN list (max. 49 entries,


beginning with the given index).

Meaning
Reset the "Configuration changed" response code, see
section 8.3.3.
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).
Immediately after the response the microprocessor of the
device will be reset.
see section 8.4.
The number of preambles insert in response telegrams can
vary from 2 to 20. Default setting is 4.
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.
Meaning
The actual parameterization is read out of the Multiplexer.
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")
The long frame addresses of up to 49 transmitters are
returned beginning at the given index.
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)
Write static data (see 131). Values out of the range 5 ... 20
will be set to 5 or 20, respectively.
Transmitters with the given long frame addresses will be
removed from the transmitter list (and the SCAN list).
The long frame addresses of up to 49 transmitters are
returned beginning at the given index.
