WinCC OA version : 3.14 P011
I am using opc da and opc hda.
I have a plan to add one more wincc oa server on the same machine.
So, I tested that both server can use opc server on the same machine.
it was not works.
I found something about opcserver and dataport.
If I use default dataport, opcserver was works, but if I change dataport, opcserver was not works.
That mean, I can use only 1 opcserver on the machine with default dataport, is it correct ?
If you have solution so that I can use 2 wincc oa server program with opc server and opc hda server on the same machine, please let me know.
I attached screen shot. ( I am trying to attached it, but it is not work with chrome browser)
1. using 9988 for dataport ( not works )
2. using default dataport ( works )

Re: OPC DA server and dataPort number
Please take into account that running 2 WinCC OA servers at the same machine is prohibited, see information in the WinCC OA Documentation:
Only one WinCC OA project is allowed to run on a system! Multiple project must not be used on the same machine!
