Configuring Communication with the Scanner
This section describes scanner side configuration for connecting the CB-EP100 to the
EtherNet/IP system. When communicating with an Allen-Bradley scanner, also refer to
the "
Configuration Procedure for Control/Compact Logix Series" (Page 5-6).
Connecting the CB-EP100 to the EtherNet/IP scanner requires the following settings:
„ Setting the IP address
Set the IP address of the scanner.
„ Registering the device profile of the CB-EP100
Register the device profile of the adaptor (CB-EP100) to be connected using the
scanner's setting software.
You can register the device profile manually or by reading the EDS (Electronic Data
Sheet) file. You can download the EDS file of the CB-EP100 from the Keyence web
site (http://www.keyence.com).
„ Configuring communication with the CB-EP100
The CB-EP100 uses EtherNet/IP cyclic communication or message communication
to communicate with the scanner.
z
Cyclic communication (Implicit messaging)
This function sends and receives data at a set RPI (Requested Packet Interval).
Selecting the communication method called "connection" and assigning the
devices to be sent and received on the scanner side enables the CB-EP100 to
communicate with the scanner without creating a ladder program.
z Message communication (Explicit messaging)
This function is used to send and receive data which does not need to be timed.
Use this function when changing the measuring instrument settings or when
performing EtherNet/IP communication with the scanner (e.g., Rockwell
Automation MicroLogix Series) that does not support cyclic communication.
This function uses a ladder program to create a message on the scanner side for
communication.
For more information on setting each communication method, refer to the chapters
titled "Communicating with the LJ-V7000 series" ( Page 3-1) as well as the manuals
enclosed with each scanner.
This manual explains only the EtherNet/IP scanner functions and settings
required for communication with the CB-EP100. For details on the
functions and settings between the EtherNet/IP scanner and CPU unit,
refer to the manuals enclosed with the scanner and CPU unit.
