I'm building a S7-300 rack to work on my Siemens Classic Step 7 programming skills. I've worked now and then with Siemens hardware, usually troubleshooting or adding small program edits, but I really don't have the depth of knowledge that I'd like to make some higher level edits in my customer's automation. I've thrown together some components that I've collected, and added some of my customer's no-longer-used or spare components. Here's a picture of the rack I'm working on today, but I'm also adding an AS-i network, and a G120C VFD through the Profibus network. I have some used HMIs to add, but one would need Profinet to connect to the CPU. Is there an inexpensive way to add Profinet to this rack, or would I need to change my CPU?
