Hello HAMEEE; Environmental conditions can certainly affect the signals on the Profibus lines, especially on the copper segments. See for example the following extract from an excellent document presenting Profibus, Catching the Process Field Bus: If you need to validate this effect and visualize the impact on the Profibus transmission, you can use an oscilloscope or a Profibus analyzer, such as the Softing Profibus Testr 5, or the Procentec ProfiTrace unit, which includes its own oscilloscope. https://industrial.softing.com/en/products/network-tester-and-analyzer/profibus-tester-5.html https://procentec.com/products/profitrace/?content-1 Sample screenshots from an oscilloscope analysis are demonstrated in the following document, along with troubleshooting results: https://sbc-support.com/uploads/tx_srcfaq/RS%20485%20Oscilloscope%20Screenshots_100179.pdf. Verification of the installation and state of connectors, cables, sensors and conduits are most important in the case you are submitting, and maintenance, especially during the rainy season, is imperative if you want to have acceptable readings in the controller. Hope this helps, Daniel Chartier |
