Post by leon78 on Codesys 3.5 SP17 Patch 2 CheckBounds (POUs for Implicit Checks) ^{CODESYS Forge talk (Post)}
Hello! I use CheckBounds (POUs for Implicit Checks). But I have a problem. I use an array as an VAR_IN_OUT of Function Block. If I try to monitor the array of variable length ([* ]), its does't work. The CheckBounds POU isn't called. If I use the array of fixed lenght ([lower..upper]), the CheckBounds POU is called. Why?

It seems that there is a limitation with the STRUCTs. Does anybody know, what’s okay to save (add to the recipe) and what’s not okay? Or is there another problem with my project? If I have only an array in the recipe definition everything works perfectly (see project).

Post by nathant on Running webvisu with Codesys Control Win V3 in Simulation Mode ^{CODESYS Forge talk (Post)}
Hello - I was wondering if I can run a webvisu in Codesys V3.5 SP 18 when using the Control Win V3 soft PLC. I don't see anything saying I can't do this, but I haven't been able to access the webvisu using conventional methods. Thanks.

Hello, I have the same issue with my cMT display. I know it's a communications issue with my Eurotherm E+PLC400 PLC using the Codesys V3 driver. Were you ever able to figure out what the problem was and if so, what was your fix. Any help would be greatly appreciated.

Hi Sir Kevin. May I know how you came up with this solution. Im a bit confused but I tried to put this. [SysCom] Linux.Devicefile=/dev/ttyRS48 (remember, no 5 at the end!) then set com port in codesys to 6. It also works for me but want to know where did you get this. Thank you.

OK, that makes sense. Because the FB is provided a specific interval period, it would change the target position accordingly based on the time it "thought" elapsed. If it has the wrong interval provided, it updates the target positions every cycle incorrectly so the axes will end up moving faster or slower. Thanks!

Post by marks on Regarding trend storage access error ^{CODESYS Forge talk (Post)}
I had this problem when running the application as a Simulation. When I wrote it to the Pi all worked as expected. If this isn't the case for you, we've seen some issues with sqlite on the Pi's - so reset Origin and re-download may help in that case. Good luck, Mark

Post by timvh on RAMP_REAL FB is retaining my output value when i try to re use the FB ^{CODESYS Forge talk (Post)}
I think, that if you set the timebase to T#0s, that it will be reset. But you can also make your own ramp down with a Timer (make sure the PT time is not T#0s):

Hello just to give more feedback the error I get is "ERROR_UNKNOWN :represents raw value of 5110" in File.DirOpen. The xDone never gets true, and I never get the listing of files (csv files in this case). In the hDir i get the value of 0 for a DWord!?

Gentleman OMG, I made a huge mistake when i tried and moved shaft by hand i hold cover(as on photo) in my fingers. I was convinced that shaft has key but it there is not key. So when i turn cover it slide on shaft. When i take off cover and drive is in standstill, shaft does not move. So everything works perfectly

Post by oymyakon on Modbus Lockup ^{CODESYS Forge talk (Post)}
Hi i have a project where i am communicating with many modbus devices using TCP to serial. This is all working extremely well except when i turn one of the remote devices off. If i leave the auto reconnect on it still doesn't talk to the rmianing devices and if i turn Auto reconnect off it locks up. Any help would be appreciated. Paul.

Post by micik on SysFileOpen not working ^{CODESYS Forge talk (Post)}
Hi, I have the same problem. Some of the libraries I created over time depend on writing files to a folders like c:\Temp. I can confirm that proposed solution is not working with 3.5.20 Patch 2. Can you please specify wich exactly .cfg file needs to be modified and in what way, in order to include c:\Temp in the SysFile path? Thank you!

Hello I have a problem with the Frame-configuration. In the picture below you can see that I set the Editor Type to variable. If it would be text it would work, but it wasnt variable anymore. Thanks for your time. Sorry, my codesys is in German.

Post by kevinrn on Signing Packages without exposing the password of the certificate ^{CODESYS Forge talk (Post)}
Indeed, I'm also seeking a solution for this issue. The main challenge we face is the requirement to use EV (Extended Validation) Certificates. Due to security considerations, it's not possible—nor is it ever recommended in such cases—to export the certificate with its private key.
