<div class="markdown_content"><p>Thanks for the quick reply.<br/> Unfortunately I do not have the original V2.3.3 installed on this PC.<br/> I tried to install but for some reason corrupted the V2.3.9 setup and so I deleted it and reinstalled V2.3.9<br/> The POU's are all in the library when viewed. <br/> I tried installing another Comms lib with the same functions but no luck.</p></div>

<div class="markdown_content"><p>change the compile program to your old one 2.3.3<br/> Use the libs of 2 years ago.<br/> and it says it can not find the pou in the lib (other name or check the lib in the window library <br/> using two libs with same functions<br/> etc.</p></div>

<div class="markdown_content"><p>Hello to all. This is my first post on the forum.<br/> I am using Xsoft-CoDeSys V2.3.9 SP2 from eaton.<br/> The target is a microinnovation screen (XV-2xx-V2.3.9 SP2)<br/> The screen is about 2 years old and had an old project on it I wanted to modify.<br/> The original program was wrote with V2.3.3<br/> On opening the original code, 3 libraries were not found. I have referenced these in the library directory's.<br/> The project compiles ok but on download I get <br/> " Unresolved external POUs:<br/> xSysComClose<br/> xSysComOopen ...etc"<br/> listing all the pou's in the syslibcom library.<br/> The libraries are the original ones as far as I'm aware,</p> <p>Can anybody help?</p></div>
