<div class="markdown_content"><p>Hello anverheul,</p> <p>this seems to be a bug in the CoDeSys manual. There are some things to configure that will not be replaced by the placeholder concept. </p> <p>One of these configurations is the name of the object for programmability. Another configuration is the path to the bitmap in a bitmap object for example.</p> <p>So, it is not possible to use a placeholder as the object name for programmability.</p> <p>A workaround could be to define your own user defined type that contains only these configurationoptions that you really want to configure. Then define a array of these structures, and configure the elements with the members of your own type and use placeholders for indices in the array.</p> <p>I hope that helps you solve your problem.</p></div>

<div class="markdown_content"><p>Hi,</p> <p>I tried to use the placeholder concept in combination with programmability. </p> <p>Background info:</p> <p>===========</p> <p>About placeholder concept (from manual): At each location in the configuration dialog at which variables or text are entered, a placeholder can be set in place of the respective variable or text. </p> <p>About programmability: this generates variables of type VisualObjectType that can be used to configure visualisation elements.</p> <p>Environment:</p> <p>=========</p> <p>I'm using CoDeSys 2.3.3.6 in combination with Advantech WinCE based IPCs.</p> <p>Issue/Question:</p> <p>==========</p> <p>It seems that it's not possible to specify an placeholder like $TEST$ as the object name for programmability. </p> <p>Doing this causes compiler errors, and also it's not possible to specify the placeholder replacements.</p> <p>What am I doing wrong? Manual says that placeholders can be used anywhere in the configuration dialog. </p> <p>Regards,</p> <p>Arie N. Verheul</p></div>
