When configuring Citect SCADA communication, the maximum number of ports for one board

Hi KANG ,
We have tested thousands of simulated power meter devices in our lab.
It looks like there is a limit of 512 ports per board (tn8321) for Modnet, but it is different for other protocols.
I think the actual limit shouldn't really matter, since to design this system properly, I would recommend creating multiple I/O Servers to host these devices. E.g. you could simply create two I/O Servers, each with their own Board, with 250 Ports defined, which each communicate to 250 end devices.
If you want a more specific answer, please let me know what protocol or Citect Driver you intend to use.
