I am unable to load a ladder logic project into this Symax 400. It begins to rack address and then I receive a transmission error 74 after about four adresses are loaded. I can access the PLC fine, it's just that I can't load the ladder logic into it. I am using sfw375 and entering the programming port on the front through a Symax rs232-rs422 converter.
My PC is running W2K. Is my PC too fast, or do I need older programming software like sfw374? I am able to load the ladder logic and the labels offline into sfw375.
Any assistance would be much appreciated.
Thanks,
Eric
