I must say a very good job well done on S7 300-400 programming training.
However, i would suggest doing the siemens TIA [Totally Integrated Automation] training which is the recent[new] siemens simatic software package plus troubleshooting will add more flare for working professionals.
I think those things are comming soon. But ass professional trainers, Real Pars people knows they must start from scratch. It´s good news to know that the even when the site changes its appearence, the mision is the same. Keep that RP! Good morning
