Table 14-32 Others properties of the ET 200iSP HART analog modules
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 eld 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 eld device respond cyclically and continuously to a pre‐
dened HART commend to send (the reading of the measured var‐
iable, for example).
(Burst mode)
No
HART master cyclically sends a predened HART command to the
connected HART eld 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 process.
(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 eld length
(data length)
64 bytes (corresponds to 75 bytes
data record in transparent-mes‐
sage-data format)
Client management
(Client Management)
No, only one client per channel
(four "mailboxes" per module)
