Posted 12 Mar 2014 I am working on a project to add a single line marquee to a process that is controlled by a PLC5/30 that has an ethernet sidecar attached. The marquee has an ethernet interface for communication to the PLC. I would like to set the marquee at my desk for trial where I have a PLC5/30, but no ethernet capability at the CPU. I was thinking about a Controllogix gateway using a Controllogix chassis with DH+/RIO and Ethernet cards for a temporary solution to allow me to do development work. So I would go out of the 5/30 DH+ port to the DH+ / RIO card, then out through the ethernet card to the marquee. The Controllogix hardware is available in one of our labs, so there is nothing to be purchased. Would this arrangement work to pass ASCII message data from the 5/30 to the marquee?
