5 USER GUIDE
[Program structure]
The program structure is shown below. With the module having the node number 1
(FL.NET module for LPU01) and the module having the node number 2 (FL.NET module
for LPU02) 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.)
When R0A0 startup is detected in LPU01 side ladder program 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 module.
This program example is a ladder program, which runs in this manner.
When using this ladder program, be sure to place the S10V in the RUN state.
