The REF 54_ feeder terminal offers up to 32 freely programmable LON inputs and
outputs on the LON bus. The inputs and outputs use the L
network variable (NV type 83 = SNVT_state) for sending and receiving process
data. The LON inputs and outputs are accessible in the feeder terminal configuration
and can be freely used for different types of data transfer between REF 54_ feeder
terminals and other devices that are able to communicate using the network variable
of type SNVT_state.
