That's the easy part. The hard part is learning the Siemens way of programming. Siemens is really good at things Allen Bradley handles horribly",

Its a assembler like language from the way-old-days where each line is a single instruction fo the CPU. It was still in commen use 10 years ago.\nTo give you an idea, what in any commen programming language is:\n\n A:=B+C //Adds B and C up and store result in A\n\n Becomes in S",

My background is mainly with Rockwell Studio 5000, so I already have experience with PLC programming, troubleshooting, and industrial automation.\n\nI need to learn Siemens STEP 7 as quickly as possible and become confident enough to work with it professionally.\n\nI have access to STEP 7 Classic (SIMATIC Manager) and can dedicate about one hour per day to studying.\n\nMy main priorities are:\n\nUnderstanding the Siemens programming structure and how it differs from Rockwell.\n\nBecoming good at troubleshooting and online diagnostics.\n\nLearning how to navigate and understand existing projects.\n\nBeing able to modify and develop PLC logic confidently.\n\nIf you were in my position, what would you do to learn as quickly as possible?\n\nWould you focus on official Siemens documentation, practical exercises, online courses, or studying real projects?\n\nAre there any specific resources, exercises, or learning strategies you would recommend?\n\nSince I already know Rockwell, I don't want to waste time learning basic PLC concepts I already understand. I want to focus on the Siemens-specific concepts and become productive as quickly as possible.\n\nI'd really appreciate advice from people who have made the transition from Rockwell to Siemens!\n\nThanks!",
