Communicate Over a Remote I/O Network
B.
To write configuration or output data to the module, enter the
following logic:
The application writes configuration and output data to
dints_output,
which is an array of
DINTs. Before the controller sends the data to the module, the FAL instruction moves the values to
int_buffer_write.
This converts them to 16-bit integers (INTs).
After the FAL instruction converts the DINTs to INTs, the MSG instruction sends the data in
int_buffer_write
to the module.
