This section gives the communications specifications, describes the control methods that you can use for communications, and describes the settings that are required before starting communications with an external device.

Basic Control Operations of the Sensor

The following figure shows basic communications between an external device and the Sensor and the flow of signals and data.

The following methods can be used to exchange data between an external device and the Sensor.

Commands That Can Be Input to the Sensor from an External Device

Type Description

Control commands

Control signals (input signals)

Communications command input

A measurement is executed when a measurement trigger (i.e., an ON TRIG signal) is input. For information on control signals, refer to Control with Control Signals and Status Signals: p.19.

Various commands can be executed, such as measuring commands and scene change. The communications commands depend on the communications protocol that you use. Refer to the section for each communications protocol for details.

Data Output to an External Device from the Sensor

Type Description

Status signals When the Sensor confirms a control signal or communications command input

and begins measurement processing, the status of the Sensor is reported to the external device through status signals (e.g., a BUSY signal). For information on status signals, refer to Control with Control Signals and Status Signals: p.19.

Overall judgement NG is output whenever there is one or more NGs in the judgement results for mul-

tiple inspection items. The overall judgement can be output through the OR signal or through the JG output parameter.

*1: This behavior can be changed in the settings.

For information on the OR signal, refer to Control with Control Signals and Status Signals: p.19. For information on the JG output parameter.

be inspection items for output and registered as output data (data 0 to data 31). Refer to the following for details.

Settings Required for Data Output: p.61, 97, 127, 153, 175, 204.

You can also use commands to obtain results after a measurement is performed. You can output character strings and numbers that are read by inspection items

such as OCR, Barcode, 2D-code, or 2D-code (DPM). Refer to 11 : p.25 for details. You can also use commands to obtain results after a measurement is performed.

Control Methods for the Sensor

There are three methods that you can use to control the Sensor from a PLC or other external device. They are described in this section. For details on each control method, refer to their corresponding section.

Control Methods

Method Overview Trigger type or area Signals or area used

Control signals and status signals

Control with commands and responses

Data output after measurements

Operation is controlled by the ON/OFF status of the Measurement Trigger Signal (TRIG) and Command Request Bit (EXE).

Control is performed by sending control commands. The execution results of the command can be confirmed in the response from the Sensor.

After a measurement is performed, the previously specified measurement data is output automatically.

ON/OFF status of the control signals and status signals

The control command code is stored in the I/O memory of the PLC and then the Request Bit is turned ON.

Not required. (Output is performed automatically after measurement.)

Overview of Communication Specifications

1 Control with Control Signals and Status Signals (Refer to Control with Control Signals and

Status Signals: p.19)

Control and status confirmation for the Sensor is performed with the ON/OFF status of the control and status signals.

This method is best suited for basic operations such as measurement tri ggers or to c heck the o perating status of the Sensor.

Control is performed by storing the control command and the response to that command in the I/O memory of a PLC.

This method is best suited to send multiple commands to t he Sensor without using PLC communi cations instructions.

3 Data Output after Measurements (Refer to Data Output after Measuremen ts: p.23)

After a measurement is executed, the measurement data specified for output is automatically output to the specified words in the I/O memory of the PLC.

This is suited to reception of the measurement result data of each in spection item.

The Sensor can be controlled from a PLC, comput er, or other external device using a variety of communication protocols. The communication protocols that can be used to control the Sensor from an external device are described below.

Control with Control Signals and Status Signals

Control and status confirmation for the Sensor is performed with the ON/OFF status of the control and status signals. Measurement triggers and other signals are input as control signals from th e PLC. The operating status of the Sensor, judgment results, and other status information can be confirmed through status signals sent from the Sensor.

(1) The external device turns ON the TRIG signal to input a measurement trigger. (2) When the Sensor confirms that the TRIG signal is ON, it outputs the BUSY signal to the external devi c e

and begins a measurement.

(3) When the Sensor finishes the measurement, it outputs the judgement results on the OR signal.

Control Signal and Status Signals

The types of signals that are input to and output from the sensor as control signals and status signals are shown below. “Use of signal in each protocol” in the table below lets you check whether or not a signal is used in each protocol. Note that this table does not show whether simultaneous use of signals in differing communication protocols is possible. For restrictions on communication protocols that can be used simultaneously, refer to

Parallel

Commands are input to the Sensor by turning the IN signals (Standard Parallel: IN0 to IN5, Parallel Interface Sensor Data Unit: IN0 to IN7) ON and OFF. There is no direct response to these commands. Confirm whether a command was received by checking the BUSY signal. The command code is input with part of the IN signals (Standard Parallel: IN0 to IN4, Parallel Interface Sensor Data Unit: IN0 to IN6), and the command is executed by turning ON the execution bit (Standard Parallel: IN5, Parallel Interface Sensor Data Unit: IN7).

PLC Link, EtherNet/IP, or PROFINET

Command/response control signals can be exchanged by storing control commands from the PLC to the Sensor and responses from the Sensor to the PLC in the I/O memory of the PLC. This enables you to send single measurement and scene switch requests to the Sensor without any sequence control with communications commands from the PLC.

Memory Areas Used by the Command/Response Control Method

Command Area You write the control commands to execute for the Sensor to this area. Response Area Y ou read the results of executing the control commands that were written to the Command Area

from this area.

Flow of Communications between the PLC and the Sensor

(1) The PLC (the user) writes a control command to a specified PLC I/O memory area (the Command Area).

Parameter Notation Examples for Command Control: p.206 (2) The PLC (the user) then turns ON the EXE bit to send the control command to the Sensor. (3) The Sensor executes the received control command. (4) The Sensor returns a response to the PLC after the control command is executed. (5) The PLC (the user) stores the response in a specified PLC I/O memory area (the Response Area). The available control commands depend on the communications protocol that is used.

TCP) Communications

Communications commands are sent to the Sensor through sequence control in the PLC. An external device and the Sensor communicate through no-protocol communications.

Data Output af ter Measurements

After a Single Measurement or Start Continuous Measurements command is executed, the Sensor automatically outputs the data t hat correspo nds t o the measurements that have been specified as output items to the PLC. This allows you to easily pass measurement results data from the inspection items to the PL C. You can also choose to output only when the PLC meets the conditions that are required to receive the data (i.e., when handshaking is turned ON). The output destination for data depends on the protocol that is used to communicate between the external device and the Sensor, as described below.

PLC Link, EtherNet/IP, or PROFINET

The output data is automatically output to the following area that is specified PLC I/O memory.

Area of Memory Used for Data Output after Measurement

Data Output Area The output data for the measurement is written to this area by the Sensor after execution of the

OR This signal outputs the overall judgement. The signal is valid when the measurements are completed (i.e.,

when the BUSY signal changes from ON to OFF). These signals output the parallel judgement output data and the calculation results of the expressions that

are set for parallel data output.

Y ou can set whether the signal turns ON for an OK or for an NG judgement in the [Judgment output condition] output setting.

Changing the Judgement Output ON Conditions: p.44

This signal is used to control the timing of reading the D signals at an external device. It is turned ON for the period of time that is required to reliably read the D signals at the external device. Set the output period so that the total output time is shorter than the measurement interval (i.e., the TRIG signal input interval). The GATE signal is output only if p arallel judgement output and parallel dat a output are set. The OR signal will be ON while the TRIG signal can be input.

Signal Function

This signal is used to input a measurement trigger from an external device, such as a photoelectric switch.

TRIG

Control Methods Using an External Device

One measurement is performed on the rising edge (OFF to ON transition) of the TRIG signal. Keep the TRIG signal ON for at least 1 ms.

Data Output Control with Handshaking

External device

(1) DSA signal

(3) Measurement results output

(2) GATE signal

Sensor

The timing for data output can be controlled through the DSA and GATE signals. The handshake function can only be used with EtherNet/IP, PLC Link, PROFINET, and parallel communication (when a Sensor Data Unit is used).

Requirements for Using Data Output Control with Handshaking

To use data output control, set the output control method to [Handshaking] in the communications protocol settings. For details, refer to Communications Specifications Settings for each communications protocol.

• Parallel Communications: Refer to Setting Data Communications Specifications: p.66.

• PLC Link Communications: Refer to Setting Up PLC Link Communications: p.124.

• EtherN et/IP and PROFINET Communications: Refer to Communications Specifications Settings (p.92 or p.149).

Handshaking

If the external device does not turn ON the DSA signal, the measurement dat a will not be outp ut to the external device from the Sensor. While the DSA signal is ON, the GATE signal turns ON when the measurement data is output from the Sensor. The external device receives the measurement data when the GATE signal turns ON.

tell the PLC when to receive the output data. This signal is sent only while the DSA signal is ON.

Overview of Communication Specifications

*1: If handshaking is not enabled for output control, the GATE signal will also be turned ON when data is output from the Sensor.

(1) The PLC turns ON the DSA signal and waits for the output data. (2) The Sensor turns ON the GATE signal when the DSA signal is ON and it is ready to output the

measurement results.

(3) The Sensor turns ON the GATE signal and outputs the output data.

Receiving Divided Output Data (Using EtherNet/IP)

In EtherNet/IP, if the data size of the set output data exceeds the data size that the Sensor can actually output in one cycle (256 bytes), the data is divided and output over multiple cycles. In this case, use handshaking as shown below to receive the multiple cycles of output data.

Example: EtherNet/IP Communications with Handshaking

Second cycle of output data

1 When the first data is received, the user (PLC) turns ON the measurement trigger and the DSA

signal.

2 The Sensor turns ON the GATE signal when the DSA signal is turned ON and outputs the first

data.

3 The user (PLC) turns OFF the DSA signal again when the GATE signal turns ON. Then, the user

(PLC) confirms the output data received in the PLC Data Output Area and moves the received data to another area in PLC I/O memory.

4 The Sensor confirms that the DSA signal is OFF and automatically turns OFF the GATE signal. 5 When reception of the output data is completed and the GATE signal turns OFF, the user (PLC)

turns on the DSA signal again and waits for the second cycle of data which could not be sent in the first cycle and was divided.

6 When the second data is output, the second data output is received when the GATE signal is

turned ON and steps 3 and 5 above are repeated.

Steps 3 through 5 above are repeated for all subsequent data output items.

Controlling Operation and Outputting Data with the Sensor's Standard Parallel Connection

This section explains how to directly connect the Sensor to external devices with the I/O cable, and control the Sensor and execute output.

Basic Operation with a Parallel Connection

This section describes the basic connections and signal fl ow with external devices. With the default settings, the Sensor operates in the following manner.

*1: You can also use the READY signal, which will turn ON when a measurement trigger can be input.

You can assign the READY signal to any output from OUT0 to OUT2. ( Getting Individual Judgements and Expression Judgements: p. 41)

• Create the ladder program to control the TRIG and IN5 input signals so that they do not tur n ON while the BUSY signal is ON. If not, a TRIG input error will occur and the ERROR signal will turn ON.

• Operation When the Sensor Power Supply Is Turned ON The BUSY signal will operate as shown below when the Sensor’s power supply is turned ON. Create the ladder program in the PLC or other external device so that the BUSY signal is ignored while it turns OFF, ON, and OFF again for up to 5 s after the power supply is turned ON.

Scene change bit

When the scene change bit (W0.00) turns ON, the scene number is input to IN0 to IN3 and IN4 is turned ON.

If the BUSY signal is OFF 5 ms after the scene number is input, the trigger to change the scene (IN5) is turned ON.

The trigger to change the scene (IN5) is kept ON for 2 ms and then turned OFF.

When the BUSY signal turns OFF to indicate that the scene has been changed, processing after changing the scene is performed (W0.01 turned ON).

Note

The amount of time it takes for a scene to change depends on the scene settings. The BUSY signal turns ON while scene change is being executed, so the scene change execution time can be checked with the BUSY signal.

If the cycle time is too long, the PLC may not be able to detect when the BUSY signal is ON. If necessary, turn OFF W0.00 after a suitable time elapses.

None: Measurement results are output without synchronizing with the external device. Handshaking: Measurement results are output while synchronizing with the PLC. Sync. output: Measurement results are output without synchronizing with the externa l device.

This setting is enabled only when the [Output control] or [Sync. Output] paramet er is set to [None]. Set the period for outputting measurement results. Set a value that is longer that the GATE ON delay plus the output time and shorter than the measurement interval. If you set a value that is longer than the measurement interval, the output timing will become delayed as measurements are repeated.

Set the time from when the result is output to the parallel interface until the GATE signal turns ON. This is the time to wait until the data output stabilizes. Set a value that is longer than the delay time of the external device.

This setting is enabled only when the [Output control] parameter is set to [None] or [Sync. output]. Set the time to turn ON the GATE signal. Set the time that is required for the external device to read the measurement results.

This setting is enabled only when the [Output control] parameter is set to [Handshaking]. A timeout error will occur at the following times if there is no response from the external device within the time that is set. When the DSA signal turns ON after measurements are completed When the DSA signal turns OFF after the GATE signal turns ON When the DSA signal turns ON after the GATE signal turns OFF

This setting is enabled only when the [Output control] parameter is set to [Sync. output]. Set the number of times to ignore the TRIG signal turning ON between when the TRIG signal turns ON and the measurement results are output.

Reading Data When the GATE Signal Is Output (No Handshaking)

The Sensor will output the measurement results without synchronizing with the external device, but the GATE signal is also output. The GATE signal is used to control the timing of when the external device reads the measurement data. Adjust the external device so that it reads the measurement results when the GATE signal is output.

Outputting Measurement Results for Data Send Requests from the External Device (Handshaking)

With handshaking, measurement results are output after there is a data send request (DSA signal) from the external device. Handshaking is effective for sequentially outputting many measurement results and it is a reliable way to transfer data.

*1 The overall judgement (OR) is output even if the DSA signal is not output by the external device.

 DSA Signal The DSA signal is used by the external device to req uest the next data t ransmission. The Sensor will not output

data until the DSA signal is turned ON. When the external device is ready for reception, turn ON the DSA signal.

Offsetting the Timing of Outputting Measurement Results

Note

The measurement result is output when the TRIG signal turns ON the number of times set for the [Number of delay] parameter. This allows you to delay the output timing of the measurement result from the Sensor according to the actual processing timing of the line.

Example: Sequential Feed Line That Uses a Star Wheel In a line like this, you can synchronize the output timi ng of the measurement result s and the discharge t iming of NG products that are detected.

2nd

4th

Result output

Discharge device

TRIG

Sensor

If you set the [Number of delay] parameter to 4, the measurement result output is delayed by four TRIG signals.

• With synchronized output, the number of times that the TRIG signal turns ON is counted. Therefore, use synchronized output only when only one measurement result is output for each measurement. (Output either the parallel judgement or data.)

• Use a measureme nt trigger only for single measurements. If you perform continuous measurements by inputting a command, the output timing will not be correct and the Sensor may malfunction.

Introduction to EtherNet/IP

EtherNet/IP is an industrial multi-vendor network that uses Ethernet. The EtherNet/IP specifications are open standards managed by the ODVA (Open DeviceNet Vendor Association). EtherNet/IP is used by a wide range of industrial devices. Because EtherNet/IP uses standard Ethernet technology, various general-purpose Ethernet devices can be used in the network. EtherNet/IP has mainly the following features.

 High-speed, High-capacity Data Exchange through Tag Data Links The EtherNet/IP protocol supports implicit communications, which allows cyclic communications called tag

data links with EtherNet/IP devices.

 Tag Data Links at Specified Communications Cycle for Each Applicat ion Regardl ess of the Number o f Nodes Tag data links (cyclic communications) operate at the cyclic period that is specified for each application,

regardless of the number of nodes. Data is exc hang ed over the network at th e refr esh cy cle tha t i s se t for ea ch connection. The communications refresh cycle will not increase even if the number of nodes is increased, i.e., the concurrency of the connection’s data is maintained. Because the refresh cycle can be set for each connection, each application can communicate at its ideal refresh cycle. For example, interprocess interlocks can be transferred at high speed, while the production commands and the status monitor information are transferred at low speed.

On a network to which many devices are connected, performance may drop (e.g., responses may be delayed or packets lost) or communications errors may occur when there is temporarily high traffic on the network. Test the operation under actual conditions before you start actual operation of the system.

Note

Data is exchanged cyclically between Ethernet devices on the EtherNet/IP network using tag data links as shown below.

Ethernet Connection

Controlling Operation and Outputting Data with an

 Data Exchange Method To exchange data, a connection is opened between two EtherNet/IP devices.

One of the nodes requests the connection to open a connection with a remote node. The node that requests the connection is called the originator, and the node that receives the request is called the target.

 Data Exchange Memory Locations The memory locations that are used to exchange data across a connect ion are specified as tags.

You can specify memory addresses or variables for tags. A group of tags consists of an output tag set and an input tag set.

To communicate by EtherN et/IP with a PLC that does not support tag data link communication, use the message communication function rather than tag data link.
