FL-Net Network Interface Module for CompactLogix

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.
