DeviceNet to SCANport Communication Module with Digital Inputs Parameters

4. Set the Peer A Input (29) parameter to a destination for the first

two words of data.

5. If using four words of input, set the Peer B Input (30) parameter

to a destination for the second two words of data.

6. If receiving Cmd/Ref input data, set the bits in the Peer Cmd

Mask (31) parameter according to the following table.

Important: If both Master-Slave data and Peer data are being used to
control the adapter, make sure you know which one is transmitting
which control bits. The adapter will receive each control bit from only
one source. This includes the stop bit.

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 Timeout (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
DeviceNet to SCANport Communication Module with Digital Inputs.
Make sure another DeviceNet to SCANport Communication Module
with Digital Inputs 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.

If receiving I/O from:

Then set bit to:

Master device (PLC or SLC)

Peer device (another DeviceNet to
SCANport Communication Module with
Digital Inputs)
