Losing Connection While Transfering Project
Hi,
When I load a project from PLCnext Engineer to the PLC, I (often) get the error message that the connection was lost and a communication error occurred during the update.
In order for the project to be transferred, I have to repeat the process several times.
I find these errors in the log (/opt/plcnext/logs/Output.log):
26.11.24 09:50:20.703 Arp.System.Commons.Net.TlsSocket ERROR - SSL_ERROR_SYSCALL while handling SslResult, Openssl error text: '' 26.11.24 09:50:20.704 CommonRemoting ERROR - Error occurs while writing data, streamError=FFFFFFFF 26.11.24 09:50:20.704 CommonRemoting ERROR - RemotingContext::AbortConnection(): connectionID=AFEE3F63, errorCode=40001004 26.11.24 09:50:20.704 CommonRemoting ERROR - RemotingContext::AbortConnection(): connectionID=AFEE3F63, errorCode=40001004
An AXC F 1152, HW 6, FW 2023.0.7 with PLCnext Engineer 2024.0.04 is used.
Comments
The problem seems to be solved by changing the connection timeout value in PLCnext Engineer to a higher value. Explained in the docs: https://engineer.plcnext.help/latest/Commissioning_TCP_CommunicationSettings.htm
