Not sure this will help you but I had the same issue and was able to activate the license on a Windows PC using the Web Depot in a web browser. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_installing_license.html

I am using a new project, with nothing, but when add a simple cam table, and compile, there will be errors. It seems some add-on or library was missing, but there is not any hint. Could you help, please.

you need to switch to a realtime capable plc. Do not map variables, this will be done by the SoftMotion. And check the Ds402 parameters in the generic parameterview on the Softmotion Connector.

Post by alex-wall on Network Variables not updating ^{CODESYS Forge talk (Post)}
This worked for me. I had four identical PLC's. Three of them worked just fine with 255.255.255.255 as the broadcasting address but the 4th would not update the variables. Changed it to 192.168.x.255 and everything worked.

okay, the weird thing is the driver is only continuous running when i enable debug output. if debug is not enabled it's continuous switching from running to not running. i will check again and download the libraries Which versions of libraries do you use, can you send a screenshot?

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
It doesn't load differently codesys seems to be behaving differently. Original version of ethercat master in project archive is 3.5.15.50, compiler is 16.4 as is codesys I'm using. It builds fine in vm and not on local machine. The reason is not obvious. It builds on local machine with ethercat master at 3.5.16.0. I'd really appreciate advice

Try OSCAT_BASIC and Function DW_TO_REAL. DWORD_OF_BYTE my although help. The Lib is open and free. It is not necessary to add this Lib, you can use/copy the source code just to get an idea.

Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.
