The AC900f communicates with the 800m via OPC, but data refresh is slow and there is lagging – what should be done?

Hello everyone, I use the Freelance2013 software to read data from 800m controllers for display on a screen. But sometimes there is data delay and lag – what’s causing this? There’s also the issue with 800m; every time I try to download a 800m program, I need to restart the computer in order to download the modified version. I’m not sure why that is Thank you
Follow these steps to troubleshoot one by one: 1. First, check whether the power supply to the controller is stable. 2. Test whether there is any attenuation in the controller’s output signal and what its filtering characteristics are. 3. Check the grounding of the controller’s circuit board. 4. Move the computer to within 800 meters of the controller in order to make the connection
It’s a bit far away; it might also be that there’s too much junk in the computer’s cache – clearing it out promptly would help.
