Delta plc changing port problem

[oqapsking]

Hello
As you know in the ethernet communication we use the ip and the tcpip port
In this case
The ip is 192.168.1.210
Port :502
My plc is delta dvp 12se
They have a software called dci soft
I can use it to change the ip
But i really need to change the port number too
If any one know how
Please tell me
With thanks

No one knows about it??

If your software doesn't have a port setting then you probably cannot change it.

You should contact the manufacturer and ask them.

PC: 192.168.1.1
PLC1: 192.168.1.2
PLC2 : 192.168.1.3

[edit] I see your problem maybe you should use VPN for connect data from network or change port to forward with other PLC such as

502 to PLC1 port 502
503 to PLC2 port 502

this what some one in plctalk site talled me to do

so i did as he said and it worked
what i did is when i opened the router to forward the port
i entered 502 for the internal port
and 503 for the external port as in the attached photo

and when i tested it to connect the plc using another internet connection
i used the port 503 and it connected normally

and i hope this will help others
this method means you can connect any device does not have the option to change the port number
