The MVI69-FLN FA Control Network communication module is a single

slot solution that allows Rockwell Automation CompactLogix processors to

communicate with FL-net protocol-compatible devices. The module

implements the FL-net version 2.00 (OPCN-2) specification, as defined by

JEMA (The Japan Electrical Manufacturers Association) for the standard

FA control network. FL-net is a master-less system.

The MVI69-FLN module acts as a gateway between the FL-net network

and the CompactLogix/MicroLogix backplane. The data transfer from the

CompactLogix/MicroLogix processor is asynchronous from the actions on

the FL-net network. The module’s internal database can be used to

exchange Area 1 and Area 2 cyclic, network, and module status data

between the processor and the FL-net network.

FL-net is a peer-to-peer networking system. All FL-net devices transfer

data using two shared databases with fixed sizes. The MVI69-FLN module

accepts commands to control and monitor the data stored in these two

databases. This data is passed between the module and the

CompactLogix/MicroLogix processor over the backplane for use in

customer applications.
