Locate Conflict-Free Resources for Your AT-FBUS
To locate conflict-free resources, you can use the Microsoft utility
Windows NT Diagnostics. This utility lists the I/O port addresses,
interrupt levels, and DMA channels that your system is currently using.
The resources not listed by this utility are conflict-free; you can use them
for your fieldbus interface. To use this utility, double-click on the
Windows NT Diagnostics icon in the Administrative Tools program
group.
