B-30 Quick Start For the 1738-ADNX
Notice the fields have been filled in for you.
• The 1756-DNB scanner will be receiving 12 bytes of data that
the 1738-ADNX produces.
• The 1756-DNB scanner will be outputting 3 bytes of data that
the 1738-ADNX consumes such as the 1738-OB4EM12 outputs.
Sometimes it is easy to get confused and reverse the numbers if
these values are entered manually (in this case, entering
incorrectly input size = 3 and output size = 12). It is a nice
feature that RSNetWorx for DeviceNet fills these values in for
you.
• On the main network, the 1738-ADNX is acting as an adapter so
it is producing those twelve bytes of data for the 1756-DNB. You
are now configuring the 1756-DNB, so those twelve bytes get
filled for Input Size as shown above.
