5 USER GUIDE
[Program structure]
The program structure is shown below. With the module having the node number 1
(FL.NET module for CPU01 or LPU/CMU01) and the module having the node number 2
(FL.NET module for CPU02 or LPU/CMU02) interconnected, cyclic transfer operations are
performed between the FL-net modules. (The FL.NET modules perform cyclic transfer
operations. The user does not have to pay attention to the operations.)
Subsequently, the node 1 module transmits a 1024-byte transparent message (TCD number =
11000) to the node 2 module. The node 2 module receives the transparent message from
node 1. This program example operates in this manner.
When running this user program, be sure to start it from CPU01 or LPU/CMU01.
