I agree. The problem is this: most companies using PLCs work in isolated networks with internet disconnected, based on confidentiality. There are many difficulties even with using git, because the structure forces you to implement features in a way that makes it hard to separate them. Branching, in particular, doesn't work well with PLC ladder logic—PLC uses proprietary binary formats that make diff tracking impossible, so you're forced into a unified development approach
