[Program structure]
The program structure is shown below. With the module having the node number 1
(FL.NET module for LPU/CMU01) and the module having the node number 2 (FL.NET
module for 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 1,024-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 LPU/CMU01.
