5.8. What is returned

Feedback messages are a copy of the original NRE command, enriched with a number of extra field-value

pairs. The

exid field stays untouched and links the feedback message to the original command.

The order of fields in the feedback message is not guaranteed to be identical to the one found in the

original command.

These are the fields that nexos adds to the feedback message:


field

value

presence description

fb-event

point name

always

The

fb-event field shows the name of the point (event)

just reached.

fb-stat

ok or error

always

The

fb-stat field reports on the status of the template

instance;

ok if everything went well up to this point, or

error from the moment an error is encountered. The

stat field will stay in this state for the rest of the

template's life cycle.

fb-info

Additional info.

optional The optional fb-info field brings additional information

when needed. With error events, the

fb-info field will

hold the asset name that caused the trouble. For sub

commands that return information (like

object-info),

the

fb-info field holds the requested information. For

most other events the field value is empty.

fb-term-sw

true

optional The feedback terminator switch field. This field is only

present for the terminating feedback message

(i.e. the final message in a command's feedback), and

when present always has value

true.

chan, layer,

sfd

always

For nexos internal use only, should be ignored.
