Fieldbus PCI-CardI/O map3.3 I/O mapDepending on the application of the system, the number of userdefinable I/O points will vary. Therobot controller I/O’s follows a basic octal numbering system, i.e. each input or output group will occurin a grouping of eight.• The NX100 system has the capability of supporting 1024 input and 1024 output signals.• The DX100 system has the capability of supporting 2048 input and 2048 output signals.3.3.1 Fieldbus input data mapThe data received from the PCI fieldbus card appears in the robot controller memory map accordingto the tables below. The base address in the robot controller where the data will appear depends onthe installation. In the examples below the PCI card inputs are represented from address 20060Memory map when the I/O size is set to a total of 24 input bits (16 fieldbus input bits)Address Contents DescriptionMSB LSB20060 Module and network status Status information.
