Enhanced DeviceNet Adapter’s Parameters
7. If sending Cmd/Ref I/O data, set the percentage in the Peer Ref
Adjust (23) parameter. The adapter multiplies this value with the
speed reference value to determine the drive’s speed.
8. Set the Peer Inp Time-out (35) parameter to the maximum amount
of time the adapter will wait for a message before timing out.
Important: This value must be greater than the product of Peer Out
Time (41) parameter multiplied by the Peer Out Skip (42) parameter
in the adapter from which you are receiving I/O.
9. Set the Peer Flt Action (33) parameter to determine what the
adapter should do if it times out.
10. Set the Peer Inp Enable (36) parameter to On.
11. Check the Peer Inp Status (37) parameter to verify operation. It
should either be Waiting (meaning it is waiting for the first Tx) or
Running (meaning it is receiving input data).
Your adapter is now configured to accept I/O data from another
Enhanced DeviceNet adapter. Make sure another Enhanced
DeviceNet adapter on the DeviceNet network is configured to
transmit peer data. Refer to the “Enabling the Adapter to Transmit
Peer I/O” section in this chapter.
Enabling the Adapter to Transmit Peer I/O
You can have your Enhanced DeviceNet adapter send I/O data to
another Enhanced DeviceNet adapter on the network.
Figure B.4
Transmitting I/O to Another Adapter
To have your adapter send output data to another adapter, you need to:
1. Ensure the Peer Output Enable (40) parameter is Off.
2. Set the Peer A Output (38) parameter to the source of the output
data.
