DeviceNet to SCANport Communication Module with Digital Inputs Parameters B-13
To enable peer-to-peer communications, you must enable one adapter
to transmit peer I/O and one or more adapters to receive peer I/O.
Enabling the Adapter to Receive Peer I/O
To have your DeviceNet to SCANport Communication Module with
Digital Inputs receive input data from another DeviceNet to
SCANport Communication Module with Digital Inputs on the
network, you must configure it for peer-to-peer communications.
Figure B.7
Receiving I/O from a Peer Device
In Peer-to-Peer communications, you can receive two or four I/O
words from another adapter. Follow these directions:
1. Enable the desired I/O and datalinks within the adapter and
SCANport product. Refer to the “Using Datalinks and Command
I/O” section in this chapter.
2. Ensure the Peer Inp Enable (36) parameter is Off.
3. Set the Peer Node to Inp (34) parameter to the number of the node
from which you want to receive data.
