Posted 14 Feb 2018 Hello everyone! this is my first post We are working with an NB and a Cp1L these devices are monitoring and storing a temperature Log in a USB memory connected to the NB. the problem comes when we insert the memory and then the HMI operation becomes very slow Any ideas why this could be happening? we tested 2 USB one was an 2.0 8GB memory and the other was a 3.1 USB which worked a little better Thank you very much for your help Share this post Link to post Share on other sites
