Use of User App Real Time Data in PLC Project

Hello,

real time data of an user app can be provided for example with the example c++ "datalayer.realtime" of the ctrlX AUTOMATION SDK to the ctrlX Data Layer:

It is also possible to read this data layer nodes with the RealTime_Data node into an PLC project with PLC Engineering:

But here now starts my actual question: How can I use this variables now inside my PLC project? I do not have a possibility to map the variables (var1, var2,...) to PLC variables like it is possible with the real time nodes under the EtherCAT master:

Could you please provide an example (PLC project and snap with source code, which provides real time data) to get an idea of how this works?

Thanks in advanced!

Hello Maurus

currently only Ethercat datas could be read/write via the realtime data channel of the PLC.

We see the problem you are facing and the development is working on a solution. But I'm afraid it will take time....

Regards

Jochen
