Post by strannik on Estun servo with codesys ^{CODESYS Forge talk (Post)}
Hello dear colleagues. I have an ESTUN PRONET servo. I'm trying to control via softmotion over the CANopen bus. There is no Ethercat bus in this servo model. In another project,using Ethercat , I controlled four axes. I have problems with ESTUN PRONET servos. A DSP-402 driver mismatch is likely. I would be very grateful for your help in solving this problem.

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
I also thought that if I had logic writing a value to this variable, then it would override the force anyway, since I thought that the force request was only applied at the beginning and end of the PLC scan. But this doesn't seem to be the case, the force persists throughout the logic regardless of what I write to the variable with logic

Post by andrej on Channel timeout CmpChannelMgr ^{CODESYS Forge talk (Post)}
Hello, I use Codesys RTE 3.5.16.5. If I connect to the PLC I often get the following message: (see printscreen) 1. Channel timeout CMpChannelMgr. 2. Closing connection CmpChannelMgr. Can you tell me, what the meaning of this is? What does the number 1250030,1220020 resp. c400:0a0a:015a:0301 refer to? I could find any information in the online help. Thanks a lot.

Post by davidmic on Is it possible to profile builds? ^{CODESYS Forge talk (Post)}
Hi I have a large project (which I can't share here), builds take multiple minutes. My computer is reasonably new (i7-10610U, 32gb ram), and I don't think my company will let me upgrade. Is there any way to profile/inspect the build process? My goal is to figure out why builds take so long, then hopefully I can make them faster.

Post by felipemsgarcia on Generic EtherCAT slave ^{CODESYS Forge talk (Post)}
Hello all, I still couldn't find the answer. I wanted to know is if there is a generic EtherCAT slave object already in CODESYS that I can use for anything, remote IO, Drives, VFD's and so on, as long as I match PDO's. Is there such an object? Thank you!

Ok, I think I understand. The problem is my language-setting being "swedish". I will check if I can switch to english. Update/confirmed. Change LANG to en_GB, this enabled the architechture to be correct and the control SL again to appear and to be possible to be updated. Thanks!

CFC (page oriented) editor does vertical scroll by mousewheel and zoom by ctrl + mousewheel, allright. How do I do the horizontal scroll (pan) using the mousewheel? (I do not want to drag the scrollbar, I am sure you have guessed by now.)

I believe the reason that I eventually lose my ability connect is because of exceeding the time limit for demo mode. Still unsure why I cannot update the edge gateway though.

Post by ofey on Codesys Soft PLC OPC UA server ^{CODESYS Forge talk (Post)}
Hi! I'm sorry if this has been asked before. I have tried looking up previous topics regaring this, but even though I'm following tutorials and other posts I cant seem to get this to work consistently. I actually got the connection established on a test project after some trial and error. I only got it to work with the "Anonymous login". But after i deleted the test project and tried to get the same thing to work on another project I cant get it to work anymore. What I'm trying to do: Set up and OPC UA Server using CODESYS with the free soft PLC. I then try to connect to the OPC UA Server with the program "UaExpert". What happens: I get the error Error "'BadUserAccessDenied' was returned during ActivateSession". What I have done in CODESYS: - Added the object "Symbol configuration" and checked some test variables - Checked "Support OPC UA features - In "Communication settings -> device -> Change runtime security policy" I have checked "Allow anonymous login" What I have done in UAExpert: - Found the OPC UA server under "local". (It is showing two servers though, I do not know why. It showed the same when it worked yesterday). Se attachment - Checked "Anonymous" under "Authentication settings in the OPC UA server. I'm new to CODESYS, so it could be something elementary wrong in my settings. Maybe something in the user settings in CODESYS regarding user rights or something?

I also would like to now how to clear the PLC Device Log. @eschwellinger are you saying there is no way to clear the log? When I am debugging I want to clear the log, it would make things some much easier to find.

Well. One can do that, I have found a python script which can modify /etc/dhcpcd.conf and I suppose there is a way I can execute it from CODESYS and it seems to be the only way
