    Assembly Sensor Cable, Optical Fiber Sensor and controller are connected through an optical fiber. - Do not shorten or lengthen the optical fibers. - Do not pull or hold the sensor on the optical fiber. - The optical fibers has a diameter of 50 µm. Do not soil the connectors, because this would lead to particle deposition in the control- ler and therefore to strong loss of light.

You can access additional submenus, e.g. for measuring rates and triggers, through the navigation bar on the left side of a web page. When programming has been completed, all settings must be permanently stored in a set of parameters to ensure that these settings will be available when the sen- sor is switched on the next time.

This feature can be useful, for example, when several sensors carry out measurements simultaneously in thickness and planeness measurements. When measuring the thickness of a transparent target using controller IFC24x1, you need to specify the actual thickness of a master object as Master value.

    Advanced Settings Encoder Inputs A maximum of three encoder values can be assigned to the measured data. They will then be issued and used as trigger conditions. This exact assignment to the measured values is ensured by the fact that exactly the encoder values are output that are exist in half of the exposure time of the measured value (the exposure time may vary due to the control).

    6.10 Trigger Mode Value input and output on the confocalDT 2451/2461/2471 can be controlled through external electrical trigger signals or commands. Both analog and digital outputs are af- fected. The measured value to the trigger point is output delayed, see Chap. 6.19.

In TwinCAT the video signal can unfortunately only be displayed as hex dump. Double clicking on the index Getvideo (0x6010.1) opens the Set Value dialog.

    Appendix |EtherCAT Documentation A 6.4.2.2 Video Signal Output via Process Data For adding the video signal to the process data, proceed as follows: Bring the IFC24x1 in the preoperational mode. Set the measurement program on video signal output (3) using the object 0x2154 (Measuring program).

    Appendix |EtherCAT Documentation A 6.5 Distributed Clock A 6.5.1 Introduction The synchronization of IFC24x1 among each other in the EtherCAT is realized via the Distributed Clock. With it it is not necessary or possible to transmit the synchro- nous signals via the synchronous input or output of the controller. Unlike the Ethernet the synchronization does not occur via external signals but about the clocks in the controllers.

  • Page 153: A 6.6 Oversampling

    Appendix |EtherCAT Documentation A 6.6 Oversampling The last arised measurement value data record is transmitted to EtherCAT Master with each fieldbus cycle during operation without oversampling. Many measurement value data records are not available therefore for large fieldbus cycle times. All (or selectable) measurement value data records are collected with the configurable oversampling and are transmitted together to the master with the next fieldbus cycle.
  • Page 154 Appendix |EtherCAT Documentation Read the PDO info on the process data tab from the IFC24x1. You can now view the size of the provided data and the mapping of SyncManager at delivery. To set the oversampling (in example 10), 10 measurement data sets (samples) selected in the PDO mapping (0x1C13).
  • Page 155 Appendix |EtherCAT Documentation Load these settings with Actions / Reload Devices (F4) in the IF- C14x1. Every process data frame now contains 80 bytes measuring data (2 measurement values per 4 bytes * 10 measuring data records). confocalDT 24x1 Page 155...
  • Page 156 Appendix |EtherCAT Documentation In order to ensure that no samples will disappear, due to the high asymmetry between master cycle and slave cycle, the master cycle time is subject to be less than the time which is required for the generation of a block consisting of x samples.

    Appendix |EtherCAT Documentation A 6.8 EtherCAT Configuration with the Beckhoff TwinCAT© Manager For example the Beckhoff TwinCAT Manager can be used as EtherCAT Master on the Copy the device description file (EtherCAT®-Slave Information) confocalDT24XX. xml from the included CD in the directory \\TwinCAT\IO\EtherCAT before the measu- ring device can be configured via EtherCAT®.
  • Page 159 Appendix |EtherCAT Documentation If ERP PREOP appears in the Current State, the cause is reported in the message window. In the example here the incorrect initialization of the synchronization manager is the reason. This will be the case if the settings for the PDO mapping in the sensor are different from the settings in the ESI file (confocalDT24XX.xml).
