ADLINK-EOS I/O Interface for the onboard digital I/O device of an ADLINK EOS-1300 vision system

Interface: ADLINK-EOS
Revision: 13.0.3
Date: 2017-11-28

General

This page provides the documentation of the HALCON ADLINK-EOS interface for accessing the onboard Digital I/O device of an ADLINK EOS-1300 vision system. Only interface specific parameters and features are described here. For general information of the operators for I/O interfaces please have a look at the HALCON Operator Reference.
Registered customers can download the latest revision of this interface from the MVTec WWW server.

System Requirements

  • ADLINK EOS-1300 vision system with Windows 7 (32-bit) or newer that is also supported by the vendor-specific SDK, also WoW64 (using 32-bit HALCON on 64-bit Windows).
  • Installed ADLINK-EOS SDK with version 1.1.1.0926 (or higher).
  • Windows: HALCON I/O interface hioADLINK-EOS.dll or hioADLINK-EOSxl.dll, respectively. If you have properly installed the interface, all these DLLs should reside in bin\%HALCONARCH% within the HALCON base directory %HALCONROOT% you have chosen during the installation of HALCON.

Installation

Only when installing or updating the interface manually follow these steps:
  • Windows: Extract the archive containing the interface files to the HALCON base directory %HALCONROOT% (Note: Administrator privileges may be required for this step). Additionally, you have to move the interface examples to the directory %HALCONEXAMPLES% manually.
  • Linux: Extract the archive containing the interface files to the HALCON base directory $HALCONROOT.

Features

  • Opening and using of multiple ADLINK-EOS I/O channels.
  • Variable debouncing filter for digital input channels.
  • Callbacks using HALCON message queues for digital input channels.

Limitations

  • No support of the encoder channels.
  • No support for configuring channels as trigger channels.

Release Notes

  • Revision 13.0.3 (Nov 28, 2017):
    • The technical dependency from the HALCON Library has been removed.
    • If the operator get_io_channel_param was called with 'param_name' the wrong number of values was returned. This problem has been fixed.
    • Added 'param_name' implementation for operator query_io_interface and query_io_device.
    • The operator query_io_device with the parameter 'channel_type' returned with no error if the IOChannelName was not specified. This problem has been fixed.
    • If the operator query_io_device was called with 'value.range' and the IOChannelName was not specified the error WIPV2 instead of WIPN2 was returned. This problem has been fixed.
  • Revision 13.0.2 (Apr 27, 2017):
    • The format of the messages sent when the value of a registered digital input channel changes has been extended.
  • Revision 13.0.1 (Apr 3, 2017):
    • First official release.
