B-6 FLEX Ex HART Module Commands
Command 130
Channel 130, Read Instrument List From Index, indicates that the long frame
addresses of the transmitters were recognized on the current loops and
returned. A zero is returned if no device is detected.
The response of this command is also used to build a cross-reference between
I/O module’s loop number and the field device’s user ID. For example, use
this in the host software’s project tree. There are no request data bytes.
