HART Multiplexer System KFD*-HM*-16
Appendix
135 Read dynamic data from up
to 7 field devices.
For the specified extended addresses, the function returns
the following data:
• The specified scan command
• Extended address
• HART data
136 Read scan status of up to
31 field devices.
For the specified extended addresses, the function returns
the scan status of the field device (0 = deactivated,
1 = activated).
137 Write scan status of up to
31 field devices.
Set the scan status for the specified extended addresses
(0 = deactivated, 1 = activated).
138 Read fault overview of up to
27 field devices.
The fault overview provides an OR combination of
communication faults and status bits.
139 Delete fault overview of up to
35 field devices.
Fault overview is deleted.
140 Read the number of
command requests and
command faults from up to
16 field devices.
Communication statistics on received or bad messages
are returned.
141 Delete the number of
command requests and
command faults from up to
16 field devices.
Communication statistics are deleted.
142 Read all communications of
the multiplexer devices.
The communication statistics concerning
the multiplexer devices are returned.
143 Delete all communications of
the multiplexer devices.
The communication statistics concerning
the multiplexer devices are deleted.
144 Number of message repeats. • Repetitions in the event of Busy report: 0 to 11,
default setting is 0
• Repetitions in event of communication faults: 0 to 11,
default setting is 2
145 Write the number of
message repeats.
146 Read the specified
scan command.
During the scan, the HART commands 1, 2, or 3 can be
executed, see above.
147 Specify scan command.
148 Read scan status. This reads or specifies the status of the scan function,
see chapter 7.3.3.
• 0: Scan function is deactivated, default setting after
a device reset.
• 1: Normal scan function is activated.
• 2: Special scan function is activated,
see command 158, 159.
149 Write scan status.
150 Read master type. • 1 = Primary master, default setting
• 0 = Secondary master
151 Write master type.
152 Read loop search type. The loop search type defines which polling address is used
to search for a device that has not responded after repeated
requests, (disappeared, see also command 129).
• 0: Single field device, 4 mA to 20 mA (single analog),
only polling address 0, default setting
• 1: Single field device, unknown (single unknown), first of
the polling addresses 0 to 15
1
• 2: Reserved for multidrop
153 Write loop search type.
