Connecting a communication cable

Connection and Configuration

 Usable cable

Wiring

The DL-EP1 uses the power supplied to sensor amplifiers, so there is no power cable wiring. This section describes the wiring of communication cables used by the DLEP1.

Use the following procedures to connect the DL-EP1 to the communication cable required for EtherNet/IP communication.

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.

Structuring a 100BASE-TX network

When the system (network) is configured with 100BASE-TX, use a Category 5 or higher STP or UTP cable. Do not use a Category 3 or Category 4 UTP cable.

2-6

• Use a STP/UTP straight cable when connecting the DL-EP1 to an Ethernet switch.

• Use a STP/UTP cross cable when directly connecting the DL-EP1 to a PC.

• 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.

• When the system (Ethernet) is configured with a type (e.g., 10BASE-2 or 10BASE-5) other than 10BASE-T and 100BASE-TX, use an Ethernet switch with an AUI (MAU) connector or a BNC connector or use a media converter (10BASE5 10BASE-T or 10BASE2  10BASE-T).

This section describes scanner side configuration for connecting the DL-EP1 to the EtherNet/IP system.

When communicating with an Allen-Bradley scanner, also refer to the "Procedures for Communicating with an Allen-Bradley ControlLogix PLC" (Page 5-6).

Configuring Communication with the Scanner

Setting the scanner

Connecting the DL-EP1 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 DL-EP1

Register the device profile of the adaptor (DL-EP1) 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 DL-EP1 from the Keyence web site (http://www.keyence.com).

 Configuring communication with the DL-EP1

 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 DL-EP1 to communicate with the scanner without creating a ladder program.

 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 sensor amplifier settings or when performing EtherNet/IP communication with the scanner (e.g., Allen-Bradley SLC5/05 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 SK-1000 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 DL-EP1 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 random 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 DL-EP1 EtherNet/IP Communication Function

 Cyclic communication

This function sends and receives data between the scanner and DL-EP1 at the set RPI (Requested Packet Interval). The function can exchange data such as the sensor amplifier's output signals and judgment values and error status without ladder programs.

Communicating with the SK-1000 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. In message communication, various parameters, including data which can be exchanged with cyclic communication, can be read and written. Functions specific to sensors such as the sensor amplifier preset function can also be executed.

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 DL-EP1 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 3-21)

Data is exchanged between the EtherNet/IP scanner, DL-EP1 and each sensor amplifier as follows:

Communicating with the SK-1000 Series

- EtherNet/IP Compatible Network Unit DL-EP1 User’s Manual (SK-1000) -

To carry out EtherNet/IP communication with a scanner which does not support cyclic communication (Allen-Bradley SLC5/05 Series, etc.), use

"Message Communication" (Page 3-22).

Usable Connections

EtherNet/IP requires that a connection must be opened from the scanner when cyclic

communication is started. There are various types of connections, and the type

usable by each device is defined in the EDS file.

The DL-EP1 can use the following connections:

・ Each connection's trigger timing is executed cyclically. The connection

type supports both point-to-point and multicast.

・ The details of each application type are as follows:

Exclusive Owner:

This connection allows simultaneous setting of both data transmission from the scanner to the DL-EP1 and data transmission from the DL-EP1 to the scanner. This setting is made not only when the scanner monitors the adaptor (DL-EP1) data, but also when it issues external inputs and rewrites the settings, etc. Multiple "Exclusive Owner" connections cannot be opened to one adaptor (DL-EP1).

Input Only:

This connection allows only data transmission from the DL-EP1 to the scanner. This setting is made when the scanner only monitors adaptor (DL-EP1) data. Multiple scanners can open an "Input Only" connection simultaneously to one adaptor (DLEP1). (* To simultaneously open connections from multiple scanners, set the Connection Type to Multicast.)

value is entered into the IN area via cyclic communication. If the judgment value is correct, the parameter range is -99.997 to +99.998. If the current value is over range, under range, or invalid, the previous value is retained without updating the current value. Use the value with the judgment value property.

(2)The properties of the judgment value (Current Value n Over Range (each bit of IN

area [6]), Current Value n Under Range (each bit of IN area [8]), and Current Value n Invalid (each bit of IN area [10]) are entered. If the judgment value of a sensor amplifier is "over", "under," or "invalid," the bit corresponding to the ID number of that sensor amplifier is set to 1. *For the SK-1000 Series, the judgment value is stored in the current value 0.

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

 What is Message communication (Explicit messaging)?

Message communication is a function that performs communication by issuing commands using the objects and services (Service Codes) prepared for each EtherNet/IP device. Message communication is used for applications which do not require the punctuality of cyclic communication, such as reading and writing adaptor settings. The objects and service codes which can be used with message communication include those which are specified as a standard and those which are unique to the device. You can use the objects and services unique to the DL-EP1 to monitor data,

Communicating with the SK-1000 Series

to read and write parameters, and to perform operations such as reset.

Message Communication

The DL-EP1 message communication function supports CIP-defined UCMM (unconnected) and Class 3 (connected) message communication.

・ In EtherNet/IP (CIP), the method called "object modeling" is used to

express a device. The device is handled as a group of objects. Objects abstractly express the configuration elements in the device. A class is a group of objects expressing the configuration elements of the same type. An instance actually expresses a specific object contained in a class. Each instance in the class has the same attribute group, but each uses a unique attribute value.

・ To execute a service for the DL-EP1, send a command from the scanner.

The DL-EP1 then returns the service execution results as a response. A command requires a service, class ID (Class ID), instance ID (Instance

ID), and attribute ID (Attribute ID)

. When a parameter is written, the

command also requires a setting (service data).

* Some of the commands to be used may not require the above items.

Once an initial reset request is executed, all parameters are stored into the nonvolatile memory (EEPROM) in approximately three seconds. When completed, the setting/status command parameter "EEPROM write result" flips to "successfully completed (1)". After the completion, "EEPROM write result" of the attributes for SK-1000 Series changes to Normal termination (1).

Changes the system parameters (the polarity of the judgment and alarm outputs and the analog output setting) to the values written in "System parameter settings" of the attributes for SK-1000 Series. To set the system parameters, confirm that the change is proper according to the connected devices and wiring. A wrong change may damage the sensor amplifier or the connected equipment.
