B-20 Quick Start For the 1738-ADNX
Scroll down and notice that bytes 0 through 11 = 12 bytes total
were enough for the input data.
This matches what you observed earlier on the main network:
The data mapped in the 1738-ADNX will be exchanged with the
1756-DNB scanner.
There are three memory buffers that the 1738-ADNX uses for
input data to the scanner on DeviceNet. The buffers are
COS/cyclic, polled, and strobed. You can map data into any of
the three buffer areas on the adapter.
Currently, all of the I/O modules are mapped to the COS/cyclic
buffer.
The primary
network knew
you were
producing 12
bytes of data.
