I am currently working on a project that involves interfacing a PLC with a ID system such as barcodes or RFIDs. I am not sure how to begin. My project consists of reading a tag on a conveyor line that will signal a CPU to make a program change. The tag will have only a number burned on to it corresponding to a program number. The layout consists of as following: The ID reader will read a tag. The reader will send the tag number to a plc. The plc will send the number to a CPU that will then make the changes to the system.
Any ideas on what type of plc to use and the background on what format the program number is going to be in when it goes from machine to machine?
