Principle of Input/Outputs in ASI
Note
For every Input or Output in ASI the respective Input/Output will be allocated (blocked).
The Inputs/Outputs of the nodes in an ASI fieldbus system can be set up as in following example:
I/O NO:
Function
Comment
25-32
8 bits of system status
For NX100 specific fieldbus status
data
33-36
4 bits of system status
For ASI fieldbus system internal
status data.
Always 4 first bits of the first node in
ASI.
37-40
4 bits of data input
Node 1
4 bits of data output
41-44
4 bits of data input
Node 2
4 bits of data output
45-48
4 bits of data input
Node 3
4 bits of data output
49-52
4 bits of data input
Node 4
4 bits of data output

Configuration interface
This interface provides a simple text based interface via the onboard RS232 interface. All network
configuration parameters are available using a standard terminal emulator such as the windows
Hyperterminal.
Note
No data exchange is halted and no mailbox activity is possible while using this interface.
Terminal emulation:
ASCII
Baudrate:
38400
Databits:
8
Stopbits:
1
Parity:
None
Flow control:
None
