[Program structure]
The program structure is shown below. With the module having the node number 1
(FL.NET module for CPU01 or LPU01) and the module having the node number 2 (FL.NET
module for CPU02 or 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 CPU01 side ladder program 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 module. This
program example is a ladder program, which runs in this manner.
When using this ladder program, be sure to place the S10mini or S10V in the RUN state.
