Well, I once almost blew up a PLC at school, such a thing (back then) did cost about more than 10,000 guilders (about 5000 euros) :shock:
It happened not to be my fault, it was some bad wiring done by another guy who installed the PLC's. And the PLC was thankfully not broken because of safety measures which are applied standardly.
I already thought the teacher to be strangely relaxed when there was a big black cloud in the classroom. :lol:
