In this section we try to explain many basic concepts about design of control systems that are not always clear and recommend some good practices on how to make the design. There are many aspects we treat: the control panel, options for redundant architectures, design of a fail safe system, different types of logics (1oo2, 2oo2, 2oo3,…), some tips when selecting I/O modules, etc. Let us know if you are interested in a specific topic.
