Post by matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi @eschwellinger yes I have been using xDoubleStorage It happened again and I checked and the files were still there with there contents, restarting codesys or rebooting would not even reload them. Doing a download and then starting the PLC loaded them and began working again. Some sort of mismatch error or something?

Post by felipemsgarcia on Generic EtherCAT slave ^{CODESYS Forge talk (Post)}
Hello Edwin, Thank you foryour answer but, I believe I was not very clear in my question, sorry. What 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 again!

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.

Hello, I'm using th IDE Combivis studio 6 (codesys based) and I get an error message when I use IO-link. "The license is missing or invalid. The API is running in demo mode." However the package Manager indicates that no licence is required. It used to work, it seems that the free package has become a paying one. Can Codeys confirm this? BR

Are you able to dynamically change the JSON message? As in, if wsValue or iValue is linked to some real telemetry that varies over time, will the JSON message reflect these changes? I am only able to send the values that I initialize the JSON message to

Im using SysCom ver. 3.5.17.0 and seem to have the same issue on a Raspberry Pi. It's not waiting for the requested number of bytes, no matter if "ulTimeout := SYS_INFINITE" or any other value. The only solution I have found is to stall the program to allow the serial port to recieve the data.

Call 10 FB instances. Connect Motor_1_Fault to the i_xHW_FaultDetected pin of FB 1, Motor_2_Fault to FB 2... By doing this, your FB will be flexible. The programming will be smooth like a perfect Drift Boss, instead of "hitting the wall" because it can't be reused!

for the package you net to install 32bit support(to have the native timprovider availble to deploy) sudo apt-get install libc6:i386 Then native Safeplc and native Safetimeprovider should be available to install. Raspi yes - but there is no official package available till now and you need have a rt_preemt patched kernel on the Pi, then it works like charm
