ControlLogix routing

The ControlLogix routing protocols use the
source routing
 model. That is, the source of a message (for example, a MSG instruction in a programmable controller or RSLinx Classic DDE topic) specifies the full route to be taken by that message. This has two significant benefits:
  • You do not need to configure routing tables in the
    bridging
     module, which greatly simplifies maintenance and module replacement.
  • You maintain full control over the route taken by each message, which enables you to select alternative paths for the same end device.
