If desired, click on the DeviceNet Baud Rate drop-down menu to change
the baud rate from the default value of 125K for the DeviceNet network.
3.
Enter the size of the Scan List I/O Entry in the field. The entry size
determines the number of input and output bytes that the EtherNet/IP
Communications Auxilliary will scan from each of the scanned devices.
The maximum Scan List I/O Entry Size supported is 50 bytes with the
default value being 8 bytes.
4.
If needed, adjust DNet IO Request Packet Interval (RPI) and DNet IO
Inhibit. DNet IO RPI determines the time it takes for data to be
requested; DNet IO Inhibit is the time used on DeviceNet Change of
State (COS) I/O. Both of these parameters are measured in milliseconds.
NOTE: Autobaud is not supported with this product.
NOTE: Auto Device Replacement (ADR) is discussed in Chapter 6 , Automatic Device Recovery
or Replace .
NOTE: Electronic keying is implemented on all scan list entries. Electronic keys are captured
when a scan list is configured form the EtherNet/IP Communications Auxilliary
webpage. The proper setting of the electronic keying becomes more important with
ADR functions and replacing units in the network.
