Analog io Controller in DeviceNet

[srinu]

Dear friends
I am devloping Analog io controller for DeviceNet application.Here i
am using 4 analog inputs ,4 analog out puts.Analog inputs are inputs
of ADC ,output of ADC is input to the DAC here iam geting a analog out
put.
I have a doubt regarding POLL IO messages . I wanted to implement the
Poll IO message .if master wants to send a command to my 4inputs and
4outputs points in my device which work independent of each other. can
any one specify me the poll I/O format for the above inputs and
outputs which should be accomadated in 8 bytes of data .Please help me
in this regard.

You have not said anything about what your application is. My initial
impression is that you are trying to use some kind of large-scale
protocol in a small-scale system.
