3. Type 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 Auxiliary 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 necessary, 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.
5. Navigate to Scan List>Configuration>Scan List to change the DeviceNet
node address of the EtherNet/IP Communcations Auxiliary.
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
Auxiliary webpage. The proper setting of the electronic keying becomes more
important with ADR functions and replacing units in the network.
