    Since relay only have 1 port number you only need to defince it once.
    Portnumbers are defined in the hardware reference guide or in the AMX PI as mentioned in the other thread.

    //on a NI 2100 relays are portnumber 4
    dvRelays = 5001:4:0

    to turn on relay 1 or 2 you just need to put this in your code:

    //turn on relay 1 and 2

    //and similar to turn off relay 1 and 2
