<div class="markdown_content"><p>Yes, if you set up a task to call them, the PRGs will turn black. </p> <p>Or, you can also call PRGs from another PRG. In ST, just type them in as if they were functions with no return result:</p> <div class="codehilite"><pre><span></span><span class="n">PROGRAM</span> <span class="n">PRG_CALLER</span> <span class="n">VAR</span> <span class="n">END_VAR</span> <span class="n">OTHER_PRG</span><span class="p">();</span> </pre></div> <p>Of course, if nothing ever calls PRG_CALLER, OTHER_PRG won't get called either.</p></div>

<div class="markdown_content"><blockquote> <p><strong>Ralph Holz hat geschrieben:</strong><br/> The grey marked POU's are never called in your application. In other words they are unused. Use them anthey will turn black.</p> </blockquote> <p>Thanks Ralph for your reply. I know that if I did not call a function in the main program they will change to gray, but I have several POUs or let's say I have several PRGs and FBs. Regarding those FBs I should call them in any PRGs then, they change to black. About PRGs how can I call them. Might be you mean that I should call them by Task configuration if it correct the problem can be solved. SO, I want to know by calling these PRGs in Task configuration then everything will be ok or I should do anything else. </p> <p>Thank you. </p> <p>Siavash.</p></div>

<div class="markdown_content"><p>Dear All, </p> <p>Recently, I am working with a source code with many function based on CR 1055 and CR 2016. When I build the code some POUs color change to Gary and when I clean them they change to black. I would be grateful if somebody tells me what the problem is?. <br/> Thanks a lot a head. </p> <p>Saivash</p></div>
