If I have to go with AB for a multiple plant layout, what would be my ultimate plant in terms of options available today? Do I head straight for ControlLogix and host all my separate PLC's in one panel? Do I head down the road of thin clients or do fat clients still hold the simplicity key? There are so many options available today I am not sure where to turn and for what advantage. So far I am thinking of DeviceNet to slc 5/05's, hooked up via Ethernet to thin clients running WonderWare. Should I be considering ControlLogix now? Is that the way forward? Can anybody shed any light on this? Is my dinner really getting cold? Guess I better go! Thanx for any input or oppinions you may have.
