2-14 What is the 1734-ADN(X) Adapter?

Cycling Node Status

Using the Cycling Node Status parameter, you can easily determine

the status of any POINT I/O modules with which the adapter is

experiencing problems. A corresponding text string appears, including

the MAC ID and a description of the status code reported in the Node

Status Table. For more information on the Node Status Table,

see page 2-23.

For the connection sizes mentioned below, the I/O connection sizes

on DeviceNet are dependent on the scanlist configuration on the

backplane.

Poll/COS Connection Consume Size shows the size (number of data

bytes) consumed by the poll/COS (Instance 2) I/O connection on the

primary DeviceNet.

Poll Connection Produce Size

produced by the polled (Instance 2) I/O connection on the primary

DeviceNet.
