EtherNet/IP and PROFINET Byte Swapping
EtherNet/IP Byte Swapping and PROFINET Byte Swapping allows you to switch the order in which bytes
are transmitted (big-endian or little-endian) between the reader and the PLC. If enabled, the bytes are
swapped for 2-byte words. When byte swapping is enabled, decoded data is stored in little-endian format.
When byte swapping is disabled, decoded data is stored in big-endian format.
Custom Ethernet Link
Important: If reader settings are not saved, do not change the reader's IP address. The IP address can
be changed after reader settings are saved.
By default, the reader operates as a server, and communicates with the host over TCP/IP for both
commands and data.
Custom Ethernet Link gives you the ability to create an Ethernet interface that is bound to the command
processor per your own requirements. You can set the Transport Layer to UDP or TCP, set the message
Type to Server or Client, and set Capabilities to Send Only, Receive Only, or Send/Receive.
Custom Ethernet Link is intended for advanced users. This feature permits the establishment of a
connection to the reader on any port, using the protocols UDP/IP, TCP, and Multicast on a specified port.
A bi-directional communication configuration is available to send commands to the reader, obtain barcode
output data, or form a single direction of communication, i.e. sending commands to the reader only, or
receiving barcode data from the reader only, without having both directions open.
In addition to the ability to move ports, you can also force the connection created by the Custom Ethernet
Link to act as a client. Instead of "reaching out" to the reader, it is possible to configure the reader to "go
out and connect to" a specified server. This increases flexibility when integrating readers into customer
applications. Without this feature, users are limited to static communication into and out of the reader
(UDP=80, TCP1=2001, TCP2=2003).
The following section will cover the implementation of how the custom Ethernet object is implemented in
an Ethernet-based reader. This additional Ethernet-based transport layer allows you to:
