Hello everyone, I'm currently using an Excel application that automatically gets values from a 1518F-4 PN/DP PLC using OPC UA. The OPC UA server is enabled in the PLC, so the Excel application is merely a Client.
I've dug a bit in the OPC_UA_ClientLibrary also provided in said link, and encountered some KeepAlive instructions that i thought might be the problem. However, i have no idea how to execute this from Excel, so either a visual basic command that keeps the connection alive, or a vbs command that executes an application which does the job. Does anyone have a reccomendation how to solve this problem? |

Are you familiar with wireshark? I would trace this behavior to check if the PLC is actively closing the connection. |
