Cognex Designer 2.0 Release
- Tasks, Sequences and Blocks
The following enhancements have been implemented. For more information on them, see the Sequence Blocks topic.
- New Sequence Blocks have been created to make byte array handling easier. These can be used when using the UserData from the FFP on the Cognex Communications Card:
- New Sequence Blocks have been created for composing and decomposing arrays, and for retrieving an element of an array, to make the handling of general arrays easier:
- New String Encoder and Decoder (to/from byte array) Sequence Blocks:
- The Notify PLC has been improved to allow setting up the input values directly on the Configuration UI and add a graphical interface to setup complex input values.
- New Sequence Blocks have been created to “manually” schedule and cancel a (scheduled) PrecisionIO event:
-
Communications
New Sequence Blocks have been created to make possible using COM port and TCP/IP communication without scripting:
Support for SLMP Protocol, similar to existing EIP and PROFINET support, has been added. For more information, see the SLMP PLC Setup topic.
Added a UI to be able to configure Precision IO events (causes and responses) for the Cognex Communications Card. For more information, see the Precision IO Configuration Editor topic.
-
Templates
It is now possible to import and export components from a project into a user library and that can be easily re-used in another project. For more information, see the Templates topic.
-
Expression Builder
The Expression Builder has been revamped. It is recommended to run a project verification that should identify any expressions that are no longer compatible.
Known differences since v1.0:
- Equality comparison between an object and a string used to perform string comparison (e.g. converting the object to string first), allowing expressions like: $myBoolTag="True". This is no longer allowed.
- Numeric values were compared as integers, e.g. 3.14 = 3 evaluated to true. This has been fixed.
- The old expression builder was culture-dependent (for example, decimal separators). The new one uses culture-agnostic parser.
For more information, see the Expression Builder topic.
-
Updated Plugins and Projects
It is now possible to automatically update a project to a newer version of a plugin it depends on. For more information, see the Updating a Designer Project To a Newer Version Of The Plugin It Uses topic.
-
Designer Launcher Enhancements
The Designer Launcher has been enhanced with two tabs, Samples and Utilities. For more information on them, see the The Cognex Designer Launcher topic.
-
Opto and Differential Trigger Signals
Switching between trigger signals no longer requires scripting. See the Switching Between Opto- and Differential Trigger Signals topic.
-
Resolved Issues in Designer 2.0
Issue Description Designer gives an error about the SQLite database Third-party applications may install (against SQLite guidelines) the System.Data.Sqlite.dll into the Global Assembly Cache (GAC). This could cause Designer to show the "Visual C++ Runtime Error" message. Memory error while saving This occurred while working with unusually big images and objects. Changing the name of a Tag assigned to a Pin is not updated in Sequence Editor When a Tag assigned to a Pin was renamed, the displayed Tag name in Sequence Editor was not updated/renamed. HMI builder hangs when using an ungroup command The HMI builder hanged when two or more HMI elements were grouped, and an additional element (type already existent in the group as well) was created and then the grouped elements were ungrouped. DS1100: The laser does not shut down when the user exits from Designer It was possible to enable the laser in Acquisition Wizard and then exit Designer with the laser on. Project file is corrupt and asks for a password when loading The saving process had to be enhanced to prevent accidental effects on the project file. Unhandled exception when closing Designer and a connected device is being renamed When Designer was closed while a connected device was being renamed the application threw an unhandled exception. Replacing and renaming tags stop working after saving and reopening the project Replacing and renaming tags in scripts did not work after saving and reloading the project until the scripts were recompiled. The Save As functionality does not transfer necessary files When Save As was used to save an existing project under another name/path, only the .cdp file was copied/renamed to the new location. This function has been enhanced to copy all files and subdirectories from the original project path as well.
Cognex Designer 1.0 PR1 Release
The Cognex Designer 1.0 Patch Release 1 did not contain any new features compared to version 1.0, only enhancements to existing features and resolved issues.
