135
Read dynamic data of up to 7
transmitters.
For the given long frame addresses the function returns the
following transmitter data:
• The selected SCAN command
• Long frame address
• HART data
136
Read SCAN status of up to 31
transmitters.
For the given long frame addresses, this command returns
the SCAN status of the transmitters (0 = SCAN disabled, 1 =
SCAN enabled).
137
Write SCAN status of up to 31
transmitters.
For the given long frame addresses, this command sets the
SCAN status of the transmitters (0 = disable SCAN,
1 = enable SCAN).
138
Read cumulative responses of up to
27 transmitters.
This command returns the OR-combination of
communication errors and status response bits.
139
Reset cumulative responses of up to
35 transmitters.
This command resets the cumulative responses.
140
Read transmitter counts of tries and
failures of up to 16 transmitters.
Communication statistic that contains the number of
commands sent to the transmitter and the number of
commands that failed.
141
Reset transmitter counts of tries and
failures of up to 16 transmitters.
Reset the communication statistic.
142
Read counts of host
communications.
Communication statistic concerning the Multiplexer.
143
Reset counts of host
communications.
Reset the communication statistic.
144
Read retry limits.
Retries in case of "Busy": 0 ... 11 (default is 0),
Retries in case of communication errors: 0 ... 11
(default is 2).
145
Write retry limits.
146
Read the selected SCAN command. During SCAN the HART commands 1, 2 or 3 (see above)
can be executed.
147
Select SCAN command.
148
Read SCAN status.
With these commands the status of the SCAN function is set
or read, respectively (see section 8.4).
0: SCAN function disabled (default after power-up)
1: Normal SCAN function activated
2: Special SCAN function activated (see 158, 159)
149
Write SCAN status.
150
Read Master type (gender).
1 = Primary Master (default),
0 = Secondary Master.
151
Write Master type (gender).
152
Read loop search type.
The loop search type defines the polling address(es) for a
transmitter that did not respond during several requests
(disappeared) is searched (see also command 129).
0: Single transmitter, 4 mA ... 20 mA (single analogue)
(only polling address 0) (default)
1: Single transmitter, unknown (single unknown)
(first one of the polling addresses 0 to 15)
Note
: The search procedure without any connected
transmitters is 16 times longer because all 16 polling
addresses are checked!
2: Reserved for multidrop
153
Write search type.
154
"Rebuild" up to 83 loops.
155
Pass through host command to
transmitter and transmitter response
to host.
By this any command can be passed to a field device and
the response can be evaluated - without any modification by
the Multiplexer.
