I currently have an associates in industrial technology which included 3 semesters of PLC programming. Those 3 semesters got me a certificate for PLC programming but honestly was far from enough training to accept a programming job. I've been working as an electrical maintenance man for the last 3 years but would like to focus more on PLCs. What would be my best option moving forward to get the training I need plus look good on paper to a potential employer? I've seen everything from taking some training courses online to getting an engineering degree and i'm not sure what the best option is. Thanks
