FLEX Ex HART Module Commands B-3
Common Practice
Commands
Device-specific Commands
The following commands provide device-specific information on the HART
I/O modules.
Command 128
Command 128 is Read Parameter Assignment of the Multiplexer. There are no
request data bytes.
Table B.2 Common Practice HART Module Commands
Command Action Meaning
38 Write Reset configuration changed
flag
Delete status information.
41 Perform device self-test Performs the device self-test
similar to turning on the power
supply.
If no error occurs, the malfunction
status message is deleted (if it had
been set).
42 Perform device reset Immediately after the command is
confirmed, a reset of the device
HART controller is performed.
48 Read Read additional device status —
