Can anyone recommend a Profibus DP slave I/O module with fast analogue I/O? I am looking for: 1) One input and one output (0-10V). (This could be two separate devices). 2) 8 bit resolution is good enough. Accuracy would be of the same order. 3) 2 milli-second or less conversion time. The speed of this device is important, and is the difficult thing to find. Most analogue I/O is much slower than this. I can sort through the other specs (e.g. input and output impedances) later once I have narrowed the field a bit. Signal conditioning could be added if required. The device may be located inside an enclosure, or externally (this is not decided yet). The input will be connected to a potentiometer and the output will send a command signal to a servo valve in a welding application. I've looked at what Siemens and Beckhoff offer, and would be interested in any other suggestions. ********************** Michael Griffin London, Ont. Canada [email protected] **********************
