Chapter 1 Controller messages
Example: Write integer values to a PLC-5 controller
If Condition_2 = 1
then reset the FAL instruction.
The FAL instruction sets INT_Buffer = DINT_Array. This converts the values to 16-bit integers (INTs).
If Control_2.DN = 1 (FAL instruction has converted the DINTs to INTs)
and Msg_2.EN = 0 (MSG instruction is not enabled)
then write the integers in INT_Buffer (3 INTs) to the PLC-5 controller.
