STP/UTP cable

Point

The CB-EP100 uses the power supplied to measuring instrument, so there is no power cable wiring. This section describes the wiring of communication cables used by the CB-EP100.

Wiring

Connecting a communication cable

Use the following procedures to connect the CB-EP100 to the communication cable required for EtherNet/IP communication.

 Usable cable

Usable cables depend on whether the system is configured with 10BASE-T or 100BASE-TX.

Structuring a 10BASE-T system

When the system is configured with 10BASE-T, use a Category 3 or higher shielded twisted-pair (STP) cable or an unshielded twisted-pair (UTP) cable.

Building a 100BASE-TX network or better 5e

Use STP or UTP cable category 5e or better to configure a network using 100BASE-TX. Do not use a Category 3 or Category 4 cable.

Connection and Configuration

• Use an STP/UTP straight cable when connecting the CB-EP100 to an Ethernet switch.

• Use a STP/UTP cross cable when directly connecting the CB-EP100 to a PC or PLC.

• Do not use the STP/UTP cross cable incorrectly because it is difficult to distinguish this cable from the STP/UTP straight cable in appearance.

• Use of 1000BASE-T Ethernet cable will not make it possible to configure a 1000BASE-T network.

Configuration Procedure for Control/Compact Logix Series

Setting the scanner

Connection and Configuration

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.

What is EtherNet/IP?

EtherNet/IP is an industrial communication network with open specifications. The specifications are managed by ODVA (Open DeviceNet Vendor Association, Inc.). Industrial protocol has been combined with the Ethernet and standardized as EtherNet/IP (Industrial Protocol). Communication is realized by combining the protocols known as Common Industrial Protocol (CIP) with TCP/IP and Ethernet. This allows regular Ethernet to be used together with the network.

Communicating with the LJ-V7000 Series

Before starting EtherNet/IP communication, one of the devices must open a communication line called a "connection" with the other device. The side which opens the connection is called the "scanner", and the side to be opened is called the "adaptor". (The CB-EP100 is an adaptor.)

EtherNet/IP includes cyclic communication (Implicit messaging) which sends and receives data periodically. Message communication (Explicit messaging) which sends and receives commands and responses at a desired timing. Cyclic communication enables you to set RPI (Requested Packet Interval) according to the priority of the data to be exchanged, allowing the entire communication load to be adjusted for data exchange. Message communication enables you to exchange the required commands and responses at the required timing. Message communication is used for applications which do not require the punctuality of cyclic communication, such as reading and writing adaptor settings.

3-2 CB-EP100 EtherNet/IP Communication Function

 Cyclic communication

This function sends and receives data between the scanner and CB-EP100 at the set RPI (Requested Packet Interval). Measurement values, judgment results and error status of measuring instrument can be transferred without the use of a ladder program.

Communicating with the LJ-V7000 Series

Configurations such as RPI and data size for cyclic communication are set on the scanner side. In a network which has many connected devices, including EtherNet/IP devices, a delay or packet loss could occur if a large load is constantly or temporarily applied on the network. Verify the settings carefully before operation.

 Message communication

Message communication can be used for applications which do not require a punctuality like cyclic communication. Various functions can be processed via message communication,such as reading or writing data which can be exchanged with cyclic communication, reading measuring instrument profiles, reading and writing measurement settings, and execute other functions unique to measuring instrument.

Cyclic communication

This section describes the cyclic communication functions and how to use them.

 What is cyclic communication?

Cyclic communication is a function that exchanges data with the EtherNet/IP device in a cyclic manner (at a set cycle). In cyclic communication, data can be exchanged when one device successfully opens a logical communication line called a "connection" with the other device. The side which opens the connection is called the scanner, and the side to be opened is called the adaptor. (The CB-EP100 is an adaptor.)

Cyclic communication is started in the following procedures:

(1) The scanner requests the adaptor to open the connection. (2) The adaptor side checks compatibility. (3) If no error occurs as a result the compatibility check, the adaptor opens the

connection. (* If an error is found during the compatibility check, the adaptor does not open the connection.)

"Checking the Device Compatibility" (Page 3-27)

Data is exchanged between the EtherNet/IP scanner, CB-EP100 and each measuring instrument as follows:
