Network variable
A network variable (NV) is a type based variable in the
Neuron-C
program-
ming language for the realisation of logical communication channels be-
tween LON
®
- nodes.
Thereby it is possible to bind one or more network variables of one or more
network nodes. Using standardized network variable types, called SNVTs
(Standard Network Variable Types) an inter-operation (manufacturer inde-
pendet) communication of the LON
®
nodes in a network is possible. If data
is transferred from a node to the network, this is made using the network
output variable (nvo), if data is transferred from the network to a node this is
made using the network input variable (nvi).
Neuron
®
-C
Neuron-C is an ANSI C standard based programming language for pro-
gramming a Neuron chip, the micro-controller in a LON fieldbus coupler,
with applications.
Neuron
®
ID
Each micro-controller in a LON
®
field bus coupler (Neuron
®
-Chip) posses
an own identification number, the so-called Neuron
®
ID.
NF/km
Abbriviation for Nanofarad per kilometer.
This is the unit for the operation capacity per pipelength.
Node
A node is a unit or a module equipped with a Neuron chip as a micro con-
troller, possibly supplemented by an external memory and I/O function. The
smallest addressing units are nodes.
