Possible Cause(s)
Device does not support HART
protocol
Device address not found by the
Adapter DTM
Device not powered
Device not wired up correctly
Device does not support HART
protocol
Device address not found by the
Adapter DTM
Device not powered
Device not wired up correctly
PLC or Remote I/O acting as primary
master forces adapter to operate as
slave
TM For control loops with
communication resistor:
Device address not found by the
HART communication DTM
For control loops without
communication resistor, for 2-wire
devices powered by adapter and for
4 wire devices:
No communication path to device
(design feature)
For all connections:
Device not powered
Battery reconnected before adapter
power fully discharged
TM Device does not support HART
protocol
Device address not found by the
Adapter DTM
Device not powered
Device powered, but shuts down
before it communicates
Corrective Action(s)
Parameters can be read from a
HART device only.
Check the highest scan address.
See chapter 5.5
Check the power supply of the
device.
Check the wiring.
Parameters can be read from a
HART device only.
Check the highest scan address.
See chapter 5.5
Check loop power.
Check the wiring of the device.
Configure adapter as secondary
master. See chapter 5.5
Configure the correct address range.
See chapter 4.5.2
Depending upon circuit, connect
modem across terminals 1 and 2
or 2 and 3.
Configure the correct address
range. See chapter 4.5.2
Check the power supply of the
device.
1. Disconnect the battery again.
2. Press button for 3 seconds.
3. Wait one minute.
4. Reconnect the battery.
Parameters can be read from a
HART device only.
Check the highest scan address.
See chapter 5.5
See second fault.
Increase power supply parameter
"Lead Time" in steps of 10 s until the
fault is eliminated. See chapter 5.8
