Posted 17 Feb 2016 Hi: maybe the problema is about the program. If the PLC does not have any program, the CPU will not work. Try to reload the program into PLC and have a look if the PLC goes to RUN. if you need some help about programming visit http://www.tecnoplc.com/ and you will find examples, documentation and how to configure S7 200 and more... Good luck. Share this post Link to post Share on other sites
