Hi, Just wondering if there are any main differences between the use of a CPU (such as a Quantum) for IO scanning as opposed to using an NOE. I know there are some differences in diagnostics, but are there any significant performance differences considering these are two different hardware types? Cheers, Henry

Performance on the built-in Ethernet port can be better in terms of scan time impact to the IOScanner service. They both support the same number of devices / maximum process image (4096 words in and out, if I recall correctly), but the scantime impact of using the built-in port will be much lower then when using an NOE.
