STP/UTP cable

Point

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.

Wiring

Connecting a communication cable

Use the following procedures to connect the DL-EP1 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.

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.

Connection and Configuration

• 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).

Insert the modular jack until a "click" is heard. The modular jack and connector will lock.

2-8

・ Keep the length of the STP/UTP cable to be used 100 m or less. ・ Carefully check the state of connector (port) on the Ethernet

switch before connecting the DL-EP1. There are various Ethernet switches. Some Ethernet switches have a different shape connector (AUI connector or BNC connector, etc.) from the RJ-45, while some have connectors used to connect Ethernet switches together (cascade ports).

Connect the modular jack on the other end of the STP/UTP cable to the

DL-EP1 connector port.

Insert the jack until a "click" is heard. The modular jack and connector will lock.

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 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.

For more information on setting each communication method, refer to the chapters

titling "Communicating with...." of each sensor amplifier 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 DL-EP1. 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.

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 FD-MH 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 time specified by the user. 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.

Communicating with FD-MH 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 adapter side checks compatibility. (3) If no error occurs as a result the compatibility check, the adapter opens the

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

"Checking the Device Compatibility" (Page 3-20)

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

Communicating with FD-MH Series

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:

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.

This example shows how to read the current value from the sensor amplifiers ID01, ID02, and ID03. (1)When the current value of a sensor amplifier is updated, the new comparator

value is entered into the IN area via cyclic communication.

* 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 current value property.

(2)The property of the current value is entered. If the current value is "over (FFFF)" or

"invalid (----)", the bit corresponding to the ID number of the appropriate sensor

amplifier is set to 1.

* For the FD-MH Series, the current value (instantaneous flow rate) is stored in the

current value 0.

 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-EP1to monitor data, to read and write parameters, and to perform operations such as reset.

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.

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).

*1 You can check the error contents of the sensor amplifier according to the ON/

OFF status of each bit. OFF(0): No error occurred. ON(1): An error occurred. Two or more errors may simultaneously occur. For details on each error, refer to "FD-MH Series User's Manual".

*2 You can check the detailed output status according to the ON/OFF status of

each bit.

*3 If the instantaneous flow rate exceeds the upper limit of the display range (if the

display is "FFFF"), data becomes an undefined value that exceeds the upper limit of the display range. If the sensor amplifier display is ErH, ErS, or rEv, data becomes "0". Without reference to the display mode set in the sensor amplifier, data for rESo mode is used.

*4 Data is read in minimum display units without reference to the integration display

unit set in the sensor amplifier. If the integration flow rate exceeds the upper limit, data retains the upper limit.

*5 If the temperature sensor is not connected, data becomes "0". If the

temperature exceeds the upper limit of the display (if the temperature display is "FFFF"), data becomes an undefined value that exceeds the upper limit of

the temperature display. *6 If the sensor amplifier display is ErH, data immediately before ErH is retained. *7 Without reference to the display mode set in the sensor amplifier, data

becomes identical to the data within the range that can be set in "rESo" mode. *8 If 100.0 is written, no warning is issued even if data exceeds the upper limit of

the display temperature range. A warning is issued only when data is less than

the lower limit. *9 If 0.0 is written, no warning is issued even if data becomes less than the lower

limit of the display temperature range. A warning is issued only when data is

greater than or equal to the upper limit. *10 If "analog output selection" is set to "standard", the free range analog becomes

invalid even if "free range analog upper limit" or "free range analog lower limit"

is rewritten. *11 The read character string is stored as ASCII code.

Reference

To carry out cyclic communication with multiple PLCs using the InputOnly connection, the DL-EP1 input data must be sent as a Multicast packet. With ControlLogix, the DL-EP1 transmission is fixed to Multicast packet. However, caution is required when using devices, such as KV or SYSMAC, for which the connection method can be selected from Multicast or Point to Point.
