Configuring the DeviceNet Network
Input and Output Tab
DeviceNet Bits
DeviceNet bits are user-defined bits that are assigned within the inputs and outputs tabs.
These bits are used with specific assembly blocks to transfer data via the polled connection.
DeviceNet bit numbering is the same for all assembly blocks selected; therefore, DN bit 0 MR
(Master Receive) under “Index Sel (User Def)” is the same as DN bit 0 MR (Master Receive)
for “Index Type.”
Figure 7: Inputs Tab
Multiple assignments may be made to the same DN bit, and the same I/O function may be
mapped to a DN bit as well as to an I/O assignment. This allows the user to indicate drive
status simultaneously to multiple devices via hardwire and DeviceNet. When multiple
assignments are made, the DN bit is the logical OR condition at he assigned input function.
