Device-specific Commands
Device-Specific HART Module Commands
Command Action Meaning
128 Read Read parameter assignment of
the multiplexer The current parameter assignment is read from the multiplexer
129 Read loop status The status of the current loop can be read with this command. The following
information is supplied:
•Hardware fault
•Rebuild running for this loop
•SCAN activated for this loop
•Searching for the transmitter because it has disappeared
•Transmitter not responding (disappeared)
•Transmitter responding again (appeared)
•Another one responded instead of it (mismatched)
130 Transmitter list The address of the transmitters that were recognized on the current loops are
returned
131 Read Read static data of 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 Write static data of transmitters Write static data (see bit 131). A preamble length outside of the range 5…20 is set
to 5 or 20
133 Delete transmitters from the
transmitter list Transmitters with the given long frame addresses are removed from the transmitter
list and the SCAN list
134 Read Read SCAN list The extended addresses of the transmitters are returned
135 Read dynamic data of
transmitters For the given long frame addresses, the function returns the following transmitter
data:
•Selected SCAN command
•Long frame address
•HART data
136 Read SCAN status of the
transmitters For the given long frame addresses, this command returns the SCAN status of the
transmitters (0 = SCAN disabled, 1 = SCAN enabled)
137 Write Write SCAN status of the
transmitters For the given long frame addresses, this command sets the SCAN status of the
transmitters (0 = disable SCAN, 1 = enable SCAN)
138 Read Read error overview of the
transmitters Thou slain returns ORed communication errors and ORed status bits
139 Write Delete fault overview of
transmitters This command returns the OR combination of communication errors and status
response bits
