Hello KhanhLe, noise can either be induced via power supply or data cable. Normally there are integrated filters to suppress noise, but maybe in your case these filters are not working. That would explain why the panel works in company (clean signals there), but not in factory (noisy environment). As many things are influenced by software parameters you could try to reset the panel to facory settings, before you send it to repair station. How do you do an "Operating system update" (OS update) or "Reset to factory settings" on operator panels? regards |
