How to improve write operations to a ControlLogix processor?

Use the PLC-5 mapping feature in Logix Designer application to improve write operations to a ControlLogix processor. To do this, map a tag array to a Data File number. In RSLinx Classic, create an OPC/DDE topic that points to the ControlLogix processor, but change the Processor type to PLC-5. In your client application, reference the associate tag items by writing to the PLC-5 mapped file and the controller handles routing the data to the appropriate tag array. For further information on how to set up the PLC mapping in ControlLogix, refer to Tech Note A9178.
