I need to monitor an active connection between Codesys(PC) and a PLC. I have tried monitoring active visu clients, but unfortunately this doesn't work. I think this is most likely because the PLC is an embedded system and most importantly doesn't have a display for Visu.
Monitoring active visu clients on a display works no problem.
Is there an easy and light weight way of monitoring an active connection between Codesys (PC) and PLC via code? I was really hoping there might be a system variable showing connection state - is there any such variable?
I have considered whether I can monitor port 1217 just to identify whether packets are being exchanged, but I'm not sure this would be possible?
Any ideas would be greatly appeciated!
Best regards,
John
