Introduction

1-1 FQ2-S4-series Vision Sensors

The FQ2-S4 Series features Vision Sensors with integrated cameras and controllers. They can be used to easily achieve simple inspections and measurements and to easily read and verify IDs. You can use parallel controls, no-protocol communications on Ethernet, PLC Link communications on Ethernet, and EtherNet/IP communications on Ethernet as standard features. You can also use a Data Unit to enable control with full-scale parallel communications or RS-232C communications. To set up and monitor the Vision Sensor, you can use either the Touch Finder or the PC Tool running on a computer. For actual operation, you can use the Vision Sensor on a stand-alone basis.

This cable connects the RS-232C Interface Sensor Data Unit to an external device.

Installation and Connections

*1: The shape and dimensions of the Ethernet connector plug and jack are specified in ISO/IEC8877:1992 (JIS X 5110:1996) and RJ-45 of the

FCC regulations. To prevent connector connection failures, the structure of the jack of this product does not allow insertion of plugs that do not comply with the standard. If a commercially available plug cannot be inserted, it is likely that the plug is non-compliant.

Important

Do not connect network devices other than PLCs on the same network as the Touch Finder or computer. If another device is connected, the responsiveness of displays and settings of the Touch Finder or computer may become slow.

Installation

The X axis in the above optical diagrams represent field of view (mm)*1. The Y axis represents the camera installation distance (mm) or WD (mm). These optical diagrams show the relationship between the detection range and installation distance for different CCTV Lenses. The values vary for each Lens. Pay close attention to the Lens that you are using when you refer to these optical diagrams. The macro ring thickness to be used is given as, for example “t5.0,” on the graphs. “t0” means that a macro ring is not required. “t5.0” means that you must use a 5-mm macro ring.

Field of view

*1: The Y axis in the optical charts represents the height of the field of view.

Example: If you use an 3Z4S-LE SV-2514H Lens for a measurement object that requires field of view of 35

mm, the camera installation distance must be 200 mm and a 2-mm macro ring is required.

The lower the shutter speed/gain and brightness settings are, the darker the image becomes. If the Sensor is used in a dark environment, make sure that the darkness of the image does not cause the measurements to be unstable.

Improving the Image Quality of Metallic and other Shiny Surfaces

When objects with shiny surfaces are being measured, the lighting may be reflected off the surface and affect the image. To remove reflections, one of the following two functions can be used.

Function Description

HDR (High Dynamic Range) If objects have contrasting light and dark areas, the dynamic range can be made wider to

Polarizing filter (for Sensors with Built-in Lighting)

HDR Function

The HDR function is used for objects that have a large difference between light and dark areas. For this kind of object, clear images cannot be achieved with the standard brightness setting. The HDR function combines several images of different brightnesses (shutter speed) so that the resulting image has a lower degree of contrast and can be measured stably for the desired characteristic.

Inputting Images with a Limit Range of Brightness

improve the quality of the images.

Specular reflections can be eliminated from an image by attaching a polarizing filter to the Sensor. If the measurement object must be moving, use a polarizing filter. Also, if reflections cannot be sufficiently removed by using the HDR function, use a polarizing filter as well.

Combining Images to Create an Image with a Wide Dynamic Range

Taking Images

Observe the following precautions.

• Use the HDR function only for objects that are not moving to avoid image blurring. Several images are taken with different shutter speeds and combined. If the object moves while the image is being taken, the image will become blurred.

• Images with different brightnesses are combined, so the resulting image will have a lower degree of contrast.

3-4 Adjusting the Timing of Taking Images

Delaying the Image Capture Timing from the Trigger Input

If the measurement object is moving, the position in the image of the feature that is to be measured will depend on the timing of the trigger signal. A delay can be applied from when the trigger (i.e., the TRIG signal) is input until when the image is taken to synchronize the timing of image capture with the speed of moving objects. If the object position varies in the image, this delay cannot be used to make the object position more stable. When you use a trigger delay with external lighting, you will also need to adjust the timing to turn ON external lighting.

Adjusting External Lighting Timing

When you use a trigger delay, you must adjust the timing to turn ON external lighting so that it matches the trigger delay timing.

Using a Strobe Trigger Signal to Control External Lighting

If a Sensor Data Unit is connected, you can change the output time of the strobe trigger signal (STGOUT) to adjust the timing of the external lighting.

[Image] − [Camera setup] − [ ] − [Lightning control]

Preventing Mutual Interference of Multiple Sensors

When the same trigger signal is input to multiple Sensors, the lighting from one Sensor may affect the measurements of the other Sensors. This is called mutual interference. This kind of interference can be prevented offsetting the image input timing of each Sensor from when the trigger signal is received. Example: A trigger (i.e., the TRIG signal) is input to Sensor 0 and Sensor 1 at the same time.

Sensor 0

Sensor 0 immediately begins image input when the trigger is input. Sensor 1 begins image input after the specified time has passed.

3-5 Adjusting the Images That Were Taken

Image Adjustment

You can adjust the image that is taken by the Sensor to make it easy to measure. There are mainly the following two types of items that you can use to adjust the image.

• Filtering the Images (Filter Items) These items filter the image by eliminating image noise with filters to make them suitable for measurement.

• Compensating for Position Offset (Position Compensation Items) These items compensate for offset in the position or orientation of the image.

You can combine several filter items and position compensation items to adjust the image that was taken. (You can use a total of up to eight filter and position compensation items combined.)

Flow of Image Adjustment

The image that is taken by the Camera (called the Camera image) is adjusted in the order that the filter and position compensation items are registered.

Note

You can specify the order of image adjustment by registering the items in the desired order, but you cannot change the order of the items after you register them.

Note

Specify the Camera image for the first filter item for image processing. If you execute more than one filter item for the image, set the source image for the other filter items to the previous image. Also, you can perform image processing with filter items only to enable processing with position compensation items. In that case, only the position information from position compensation is applied to the image to be measured. For details, refer to Using Filter Items for Processing with Position Compensation Items on page 77.

Filtering the Images (Filter Items)

You can filter the images that are taken by the Camera to make them easier to measure. This is used in the following cases.

• To cut unnecessary backgrounds so that they are not measured

• To remove noise

• To stably find the edges of marks when other edges have been clearly extracted

Compensating for Position Offset (Position Compensation Items)

Use position compensation items if the position or orientation of the measurement object is not consistent. When you use a position compensation item, the offset between the reference position and the position of the object is calculated and the position of the measurement region is corrected before measurements are performed.

Applicable Position Compensation Items

There are the following two types of position compensation items that vary in the method that is used to detect the object.

Ty pe Description

Model (model position compensation)

Edge position comp. (edge position compensation)

A search is made for a characteristic pattern to detect and correct the position.

4-4 Reading and Verifying Character Strings

Character String Recognition

Character recognition is used to read characters in input images as character information based on font information that is registered in the Sensor in advance. The characters that were read can be output to an external device. You can also verify the character string that was read to see if it matches a character string that was registered in advance or the read result from a Bar Code, 2D-code, or 2D-code (DPM) inspection item that was executed before the current inspection item.

Setup Procedure for Character Recognition

The setup for character recognition is performed in the following order.

The basic settings to recognize characters are made.

Teaching

Judgement conditions

Verification conditions

• Character format (number of characters, alphanumeric characters or symbols, etc.)

• Measurement region

• Detailed parameters to recognize characters (These are set automatically.)

Settings are made to check whether the characters that were read from the workpiece were recognized correctly. Differences between the references that were taught for character recognition and the actual result of reading the characters are detected and conditions are set to determine how accurately characters are read.

You can set conditions to verify that the character string that was read matches a specific character string. The character strings to use to verify the character strings that are read are registered in the master data.

Setup Procedure for Character Recognition

Setting Up Inspections

Step 1 Selecting the Inspection Item

Reading and Verifying Character Strings

Step 2 Teaching

For teaching, you specify the measurement region and the format of the characters to read (number of characters, alphanumeric characters or symbols, etc.). Detailed parameters to recognize the characters will be set automatically. Also, you can register the characters that are actually read when teaching as a verification condition in the master data.

Step 4 Setting the Verification Conditions

1 Press [TEACH]. 2 Place the characters to read in front of the camera. 3 Move the rectangle around the character string to

read, and then press [OK].

The measurement region will be set.

4 The characters that were read with the initial param-

eters will be displayed above each line.

You set the format of the characters to recognize to prevent reading similar characters incorrectly. (This display will not appear if the character format is already registered.)

• Number of characters to read in the character string

• Types of characters (letters, numbers, symbols, fixed

characters,

etc.)

Enter the types of characters in order and the number of characters according to the actual character string that was read.

Example

2012.12.20 → Line 1 ####.##.##

FQ-OCR Line 2 ??-???

*1 If the number of characters that were actually read is less than the number of characters that was specified in the

character format, it is assumed that reading the characters failed.

*2 If alphanumeric characters are directly specified as fixed characters but the characters that were read do not

match the specified characters, it is assumed that reading the characters failed.

The following table gives detailed specifications for the character format.

Reading and Verifying Character Strings

• Numbers 0 to 9

• Letters A to Z

• Symbols ‘ (apostrophe), - (hyphen), . (period), : (colon), / (slash), wildcard

Wildcards You can use wildcards to specify characters. For example, you can use wildcards to prevent incorrect recognition of 0 (zero) and O (the letter O). ?: Any character (recognized characters: any characters except for symbols) #: Any number from 0 to 9 (recognized characters: 0 to 9) $: Any letter from A to Z (recognized characters: A to Z) @: Any symbol (recognized characters: ‘ - . : / ) *: Skip (No judgement is made for the judgement conditions (similarity or stability). The detected character count is also not incremented.)
