Is there any specifix IO driver for GE PAC8000 PLC?

Hi GE Forum members!

This is the first time we are using PAC8000 PLC in conjunction with iFIX5.5 as HMI/SCADA. We are wondering if there is any specific IO driver required for iFIX communication with PLC or iFIX will directly communicate with PLC?

If there is a specific IO driver, can anyone please tell its code name and where can I download/buy that?

Thanks!
