Hello William; Both considerations are valid, depending on the point of view examined: - if you are looking from the point of view of a programmer, a network is simply a way to organize your code in sections that you can define logically, and comment properly. - if you look at it from the controller's point of view, a network is where status bits are set and reset. RLO is determined for the next network at the end of the present network; UC and CC bits are set or reset depending on the conditions of the present network... So the flow of the complete program will depend on each network as it is processed. You will find a bit more information on the mechanics of Status bits in the following document: https://support.industry.siemens.com/cs/ww/en/view/45523446 Hope this hel;ps, Daniel Chartier |
