DNI Configuration Parameters and Programming Notes
Output Split Point Example
We need 4 (3.5 data + 0.5 status) words of slave data that the master will
own, and we need to configure an additional 15 words so that other
DeviceNet products can write data.
•
Output Size = 19
•
Output Split Point = 4
The DNI’s output image will consist of:
The minimum value allowed for the Split Point is 1. If the Output Size is 32
(maximum), the resulting range of explicit output words would be 0x90 to
0xAE.
See "Output Assembly Data (Explicit, Split Point, and Slave)" on page 6-15
