Mapping Variables for Coupler

[AndreR5]

Hi,
Does anyone know how to map variables in ctrlX PLC for couples?

I can read the inputs and control the outputs in ctrlX I/Os and also from ctrlX CORE data layer and they (X110208 and X210208 ) are mapped in ctrlX PLC. The only one that is not mapped is the coupler and I don't know how to do it manually.f

You mean to control these IO's in the PLC?
You can either directly adress them via an AT statement in a GVL ( UL_Overvoltage AT %Ix8.4 : BIT;) or make assign an variable to this by double clicking the variable and find/select an already existing variable. 
If you also want to control this variable from the datalayer, you have to add the symbol configurion.

Could you add a screenshot of your IO project and of the EtherCat realtime data in the data layer, so we could better understand what is your topic about.

In ctrlX I/O I can read the inputs and see the states of outputs:

And in ctrlX CORE, Datalayer I can control outpurs:

But nothing happens in ctrlX PLC when I connect to ctrlX CORE. I believed the problame might be the coupler becouse is not mapped, but now I see that the ethernet connection is not fully configured. What to do in this situation?

Hi,
I find the problem. It was the path of ethercatmaster. Instead of 'fieldbuses/ethercat/master/instances/ethercatmaster/realtime_data', it was 'fieldbuses/ethercat/master/instances/_ethercatmaster/realtime_data'. So it was looking for something diffrent, not the path of data layer.

Thank you all for your interest!
