Product Specifications

The MVI56E-FLN FA Control Network communication module is a single slot
solution that allows Rockwell Automation ControlLogix compatible processors to
easily interface with other FL-net protocol compatible devices. The module
implements FL-net version 2.00 (OPCN-2) defined by JEMA (The Japan
Electrical Manufacturers Association) for the standard FA control network. FL-net
is a master-less system.
The MVI56E-FLN module acts as a gateway between the FL-net network and the
ControlLogix backplane. The data transfer from the ControlLogix 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.
The MVI56E-FLN module accepts commands to control and monitor the data
stored in the databases. This data is passed between the module and the
ControlLogix processor over the backplane for use in user applications.
General features include:

Master-less token control method

FA link protocol on Ethernet UDP/IP

Cyclic data transfer: Supports virtual memory Area 1 and Area 2. The cyclic
data is mapped to the modules I/O area
