VPN connection to PM583 ETH failed
I use a VPN software to connect to a PLC inside a LAN. PLC is PM583, ETH interface.
I can ping this PLC, and the Ping value between 70ms ~ 200ms.
I found that I was very difficult to login in CoDeSys, will always report the failure of the communication error. It seems that the reason is the communication delay, if there are some parameters can be adjusted for the PM583's communication in pool network conditions.
you can try one simple test: connect directly the cpu with your PC, without VPN.
The answer in ms give you the solution, that is the real cause of the delay: cpu with parameters or your VPN.
AFAIK you can not modify the communication parameters in CPU to have best performance.
Hope this help you
