In the example shown, you can see that the first module on the left is the DeviceNet
Module. The DeviceNet Module doesn’t have any DIP or DOP instances. The next
module is Mod 1. It contains the first output (Out 1) and the second output (Out 2), which
are recognized as Discrete Output Point Object (DOP) instances 1 and 2, respectively. In 1
on Mod 2 is the first input seen from the left, therefore it becomes Discrete Input Point
Object (DIP) instance 1. Similarly, In 2 of Mod 3 is the sixth input seen from the left,
therefore it becomes DIP instance 6. The table below shows the instance numbers of all
the inputs and outputs in the above example. It is followed by a blank table for you to
record your lineup.
