Just as there may be only one primary provider for
each input type, there may be only one secondary for
each input type. It is recommended that secondaries
be set up on different E2s than primaries; this way, if
a single controller fails or loses communication with
the other E2s, there will still be a usable input source
for the other E2s.

User This setting means the E2’s global data will
read (or be a “User” of) all values coming from the
network. This setting is for E2s that are not con-
nected to the sensor itself, but read the data that
comes from it.

If the application in this E2 will be using primary or
