switch communication object. Other relay function always works normally.

The switch status feedback can be used as an active or passive communication object. Active
message object, the switch status telegram is transmitted to the bus automatically when a relay state
changes. Passive status object, there is no telegram transmission after relay state changes. If you
want to learn switch status, you must read communication object. Communication object flags are
automatically set by ETS.
NOTE:
Switching state changes by manual operation are not detected.
