Hello,
Right now I am in the power generation business using PLCs. I grow more concerned about writing PLC code in systems like this as they are shipped out fast and the possible combinations for the PLC to handle is very large. The code typically has holes or product is shipped without a complete test.
As such, I am curious how other industries use PLCs. My naive vision is that although the machines may be complex, the sequence of operations is quite manageable. We constantly compete with what role the operator plays in the system. In theory, they can change breaker states, thrust the system back in auto, and it is meant to respond. I get a lot of resistance of not allowing that transition back into auto if any faults are present. Instead, most people want to just "let it ride" and see what happens. Again, my naive vision in other industries is that the machine must be placed back into a known, safe state prior to resuming.
Finally, do most of you enjoy this type of work? What are some example projects done/what other industries can I look into with PLC experience?
