How to read all PLC Variables ?

vishnu-marthala commented 2 years ago

Hello Everyone,

I couldn't find any documention or any function that gives me all the plc variables. How can show to the use in my UI all the avaiable PLC Symbols or Variables that are running on the controller? In Codesys i did it using GetAllItems() function which give all the variables along with their type and size. Is there similar function in ADS library as well?

How can i access or read all avaiable PLC Symbols or variables that are running on the PLC Controller?
Which ADS libary should i use? There is Standalone and other one as well. Dont know the difference due to missing wiki
Is there any pdf or some documentation on how to use ADS library?

thank you!

Hi, you have to request the ADS symbol upload information.

Check the sample for the TcAdsDll-API to see which ADS command is needed: https://infosys.beckhoff.com/index.php?content=../content/1031/tc3_adsdll2/124827915.html&id= https://infosys.beckhoff.com/content/1031/tc3_adsdll2/124833547.html?id=4034135013809922325
