<p>Step 1 : Clean All<br/>
Step 2 : Generate Code<br/>
Step 3 : Online<br/>
Step 4 : Download (via message box after online)</p></div>Very slow downloading of a project which has 10 000 function blocks2020-02-27T13:50:09.044000Z2020-02-27T13:50:09.044000Zberendejhttps://forge.codesys.com/u/berendej/https://forge.codesys.com640dd30a2ed80a3eb46267fb796a820685098a7b<div class="markdown_content"><p>A project has 10 000 function blocks each of which is mapped onto output channel.<br/>
Compilation is quite fast ( Build -> Rebuild )</p>
<p>1 - I initiate downloading ( Online -> Login )<br/>
2 - A message box "Application 1000_points does not exists on<br/>
device 'Device' do you want to create it and proceed with download ? <br/>
3 - I click OK.</p>
<p>4 - Status bar has a string "locate global data" for about 25 minutes.<br/>
5 - A message box "No connection to the device, Please rescan your device" appears.<br/>
6 - I click OK.</p>
<p>7 - Status bar has a string "Generating code I104_GVL_1__GVL__INIT" for about 2 minutes<br/>
8 - A message box "No connection to the device, Please rescan your device" appears.<br/>
9 - I click OK.<br/>
10 - At this stage, if I will do nothing, then nothing will ever happen.</p>
<p>11 - I do: Online -> Login again. <br/>
12 - A message box "Application 1000_points does not exists on<br/>
device 'Device' do you want to create it and proceed with download ? <br/>
13 - I click OK.<br/>
14 - After 2 minutes application starts.<br/>
15 - After 3 minutes dialog box "OutOfMemoryException" appears. I click OK.<br/>
16 - Application continues its work.</p>
<p>If I do "Remove application" from controller - it removed quite fast.<br/>
If I download it again, then application starts quite fast ( approx. 45 seconds )<br/>
I can do several cycles "Remove application" -> "Download (Online->Login)<br/>
and always it starts quite fast.</p>
<p>But if I close CoDeSys IDE, and start it again then the same application<br/>
will download slowly again as described above from paragraph 1.</p>
<p>The project with 5000 same function blocks starts in 1 minute.<br/>
With 10 000 function blocks in 30 minutes. So every 5000 f.b. multiply <br/>
download time in 30.</p>
