DEFINE_DEVICE
Relay1 = 5001:8:0
Relays2 = 5002:8:0

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
on[dvRelays,1]
on[dvRelays,2]

//and similar to turn off relay 1 and 2
off[dvRelays,1]
off[dvRelays,2]
