General Information on Communication via EtherNet/IP
The read head communicates with the controller (e.g., PLC) via EtherNet/IP. An object-oriented
fieldbus system for exchanging data between nodes based on Ethernet technology.
The management and development of the EtherNet/IP standards are subject to the Open Devi-
ceNet Vendor Association (ODVA). More information on EtherNet/IP will be supplied on
request by the Open DeviceNet Vendor Association (ODVA) at the following Internet address:
ODVA, Inc
4220 Varsity Drive, Suite A
Ann Arbor, MI 48108-5006 USA

The basic properties of the interface are:
•
Transfer rate 10 Mbit/s or 100 Mbit/s, half or full duplex operation
•
Automatic negotiation of the transfer rate and the duplex method (auto-negotiation)
•
Automatic setting for crossed lines (auto-crossover)
EtherNet/IP protocol works according to the CIP protocol (Common Industrial Protocol) and is
used to control, configure, monitor, and collect data. Time-sensitive data exchange (implicit
messaging) takes place using the UDP/IP protocol and non-time-sensitive data exchange
(explicit messaging) using the TCP/IP protocol.
The read head supports the following features:
•
"Listen only", "Input only", and "Exclusive Owner" connection types
•
Message transmission as "Multipoint data transfer" (Multicast) and "Point-to-point data
transfer" (Unicast)
•
Cycle time (request packet interval)
2 ms
•
Dynamic Host Configuration Protocol (DHCP)
•
Device Level Ring (DLR)
•
Address Conflict Detection (ACD)
The read head is integrated in the network via a EDS file (electronic data sheet) with a configu-
ration tool such as RSLOGIX5000. The EDS file contains all of the information about device-
specific parameters and operating modes.
Downloading the EDS file
You can find the relevant EDS file in the
Software
section of the product detail page for the
device.
