We're in the process of designing a new system which contains the following networking components:
1) A 66AK2H14/12 (for number-crunching)
2) An IO board (leds, LCD, buttons, etc)
3) An external controller (like a PC, used for configuration).
We'd like to have the system divided into 2 separate networks (eg, they have to be completely isolated and will use different subnet masks):
1) The IO board (2) connects to the 66AK2H14/12 (1) on a private network, such that the the IO board can be controlled by the 66AK2H14/12.
2) The 66AK2H14/12 connects to the external controller (3).
When looking at the 66AK2H12, we noticed it has a built-in switch but only a single a NETCP which connects to it. My question is if we can configure this switch in such a way that we create 2 networks and such that the 66AK2H12 is part of both these networks and such that it can "talk" to both the external controller AND to the IO board. The external controller should only "see" the 66AK2H12 and nothing else.
We noticed some VLAN bit-mask: is this something we could use?
The 66AK2H14 seems to have 2 switches built in and 2 NETCPs, so this should definitely work for us....but it is also quite a bit more expensive.
Thanks,
