This document describes how to use the Routing Path field of the Allen-Bradley
Native Tags via L5K file drivers.
Red Lion Controls CR1000 Human Machine Interface (HMI), CR3000 HMI, Data Station Plus (DSP), G3 HMI, G3 Kadet HMI, Graphite® Controller, Graphite HMI, Modular Controller, and ProducTVity Station™
The Routing Path is required when the CPU with the required data is not in the same rack as the Ethernet communications module.
Crimson® 3
By default, the Native Tags via L5K File Enhanced driver communicates to a processor in slot 0 of the same chassis which contains the Ethernet module. The Routing Path allows for a connection to a processor in a different slot or even in a different chassis. It is a series of comma delimited numbers, and potentially IP addresses, that directs the data from port to port between the communication modules from the Ethernet module and the target processor.
The numbers represent module ports, slot locations, as well as node or IP addresses. This comma delimited string is sent after the IP address, of the Ethernet module that the Red Lion will connect to, indicating the final destination of the packet.
The data sent from the unit running Crimson needs to be sent to the Ethernet module’s IP address (10.10.4.120), to the backplane of the rack (which is port 1 of all modules), to the CPU in slot 6. The Crimson Routing Path should be set to: 1,6
Figure 1, below, represents a 2 rack system where the Ethernet module and CPU are in separate racks; the two racks are connected via ControlNet. The data sent from the unit running Crimson needs to be sent to the Ethernet module’s IP address (10.10.4.120), to the backplane of the rack (which is port 1 of all modules), to the ControlNet module in slot 6, out of port 2 (the ControlNet port) to ControlNet node 10, to the backplane (port 1 again), to the CPU in slot 2. The Crimson Routing Path should be set to: 1,6,2,10,1,2
