Redundant Process Gateway

Redundant Process Gateway

Hi,
I want to run two DNP3.0 Process gateways in redundant, so that If one fails other can response. But they both should not respond at the same time.
I will be running the gateways on seperate machines, having Windows 7 as OS.
The gateways will be responding to a dispatcher. I do not have the facility of auto turn-over at dispatcher's end. So the turn-over has to be done on the substation level only.
If this is possible let me know the procedure.
