Dear colleagues! Faced OPC communication problem. Dispatch PC (Win10, Wincc V7.4 SP1 see attachments) collects data from objects. Out of 6 objects, two of them are implemented through a virtual machine (Oracle VM Box, with Win7, Wincc v7.2, since existing PLCs do not support communication with new software). The rest of the PCs have Win10 with the same version of software and hardware. The essence of the problem is that the Disp PC that collects data, after a certain time, disconnects all OPC objects, does not even show the time of the last update of the values, although OPC sees the connection, you can even enter. Also, after this incident, you cannot restart the project, nothing moves. Hard reboot only. And after reboot everything is fine. The whole situation started after the virtual machines were connected. Can anyone help pinpoint the problem? Attached log files and screenshots.Thank you in advance. And I apologize for my english AttachmentDesktop.zip (115 Downloads) |

Hello Sultan87718219638, if it work a certain time, and then not, and work after reboot You should use the SIMATIC Assessment Suite - Data Collector (SAS-DC) https://support.industry.siemens.com/cs/ww/en/view/65976201 Then create a Servicerequest, and send the data to the Regards Georg Berghof |
