Hello, I'm developing an application that communicates with 2 LOGO! 0BA7 devices to get input states and few other operations. I'm using S7-200 PC Access OPC server and I set up one group for the data coming from both the devices. When both LOGO are connected everything works fine, but I have some problem in case one of them gets disconnected. If it is disconnected just for a few minutes, everything is still fine: I get data from the LOGO that is connected and quality=0 for the other one. The problem is that if the LOGO stays disconnected for a couple of hours, the system stop reading data also from the device that is connected. I checked the windows registry and saw that at that time an error occurred in the application COMM200L8Host.exe. I attach the information about the error. I'm running windows 7 professional, 64 bit, PC Access v1.0.6 sp6. Has anyone any idea on why I get this error and how to avoid it? Thank you. A

I whould not disconnect from the network. Why you do this? I belive PC access tries to connect some time and if not sucesful, stops communication. |
