Properties
Explanation
Secondary master cannot be connected
(Secondary master exclusion)
No
After a Write Request there is direct feedback on the validity of the
data.
(Application Supported Parameter Check)
Yes
Several HART field devices are supplied by means of a single line.
(Multi-Drop Mode)
No, analog value =0
Communication type with HART, in which the master requests that
the HART field device respond cyclically and continuously to a
predefined HART commend to send (the reading of the measured
variable, for example).
(Burst mode)
No
HART master cyclically sends a predefined HART command to the
connected HART field device.
(Scan mode)
No
Use of the compact data format
(Compact HART Message Format)
Yes
A HART client sends a sequence of HART commands. No other
client can interrupt this procedure.
(Successive HART Commands mode)
Yes
Parameters are stored retentively.
(Parameter Stored Non Volatile)
No
Automatic deactivation of burst mode
(Burst-Mode Auto Disable)
No
Maximum data field length
(Data length)
64 bytes (corresponds to 75 bytes
data record in transparent-mes‐
sage-data format)
Client management
(Client Management)
No, only 1 client per channel
(4 "mailboxes" per module")
