I'm a Controls Engineer and have exclusively used Allen Bradley for 8 years. Outside of my job, I was asked by a new start up brewery if I could help with some PLC and HMI issues they are having. I'm anxious to lend a hand, but unfortunately it's all Siemens and I don't have any experience with it. I'm sure I'll be fine once I'm able to communication with the PLC, but the software and license are my concern. My biggest hurdle is determining what software I need and hopefully finding a free version I can use. The PLC is a Simatic S7-1200. I found a link on Siemens for a free 21 day trial for TIA Portal and WinCC, but wanted to make sure that was my best option. If anyone could offer any advice, I would greatly appreciate it!
