Configuration Assembly Object
The ABR EtherNet/IP implementation does not support an assembly object Configuration instance. However, one is
required for the creation of implicit Class 1 connections on a ControlLogix
is defined as instance number 128 (0×80). Its size is zero.
Requested Packet Interval (RPI) Value
The ABR reader can operate with Requested Packet Intervals between 2 and 3200 milliseconds. The default set in the EDS
file is 50 milliseconds. Setting this value faster than needed may hurt reading performance. If your message strings are over
128 bytes, it will take multiple packet intervals to transfer the message in 128 byte fragments. At the default 50 milliseconds
setting, a 300 byte message string would take 100 milliseconds to 150 milliseconds to transfer completely.
8.2.2 Configuring the ABR for Ethernet/IP in Barcode Manager
After Ethernet/IP is added to a configuration's protocols (see
there is an option to configure settings specific to this protocol. Click Ethernet/IP in the left side Configuration panel, and
select the desired option under Keep Read Item in the right side Control panel.
Keep Read Item allows managing the last code read and placed in the output buffer towards the EtherNet/IP host, in cases
of re-connections to the network. The default setting will likely work for most applications. The options are:
•
Keep Always—After the last code in the output buffer is read by the EtherNet/IP server manager (host), it remains in
the output buffer.
•
Discard After Connection (default setting)—After the last code in the output buffer is read by the EtherNet/IP server
manager (host), it remains in the output buffer until the connection ends, then it is deleted. In this way it will not be
re-read by the same host (or any host) in case of a re-connection.
