LONWORKS Network
An FX16 controller fitted with a LON communication card enables the
FX16 to send and receive data to and from LON controllers on a
LONWORKS network. The FX16 controller can also send data on request
to a supervisory system or a supervisory controller fitted with a
LONWORKS network interface card.
The FX16’s LON network profile is defined along with the control
application using FX Builder. You can configure the Network Variable
Input (NVI) and Network Variable Output (NVO) points in the network
profile of the control application using a LONWORKS network
management tool (binding tool). This allows the NVI and NVO to
transmit and receive data over the LONWORKS network.
A network of FX controllers fitted with the LON communication card
can share data on a peer-to-peer basis. The network supervisory
controller is not required to pass data from one controller to another.
LONWORKS Network Profile Limits
The FX16 LONWORKS interface can expose up to 62 Network Variables
(NVIs and NVOs) and up to 100 Configuration Parameters (CPs) to the
LONWORKS network. This limitation is imposed by the LONWORKS
Neuron processor on the communication card.
