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
