TwinCat3 Build 4020.28

[RedOne]

Hello,

Does anybody know if there's a variant to disable and enable automatically the modules on the EtherCat, for TwinCat3 Build 4020? 

I saw that starting with build 4024, there is a posibility to use the Project variant, and I was thinking maybe there is something that can be used also on this older build.

Thank you!

This is a good way that the bus is running, when the modules are not there.

The more complex thing is to adjust the EtherCAT slaves in the OpconEcMasterBase. You have to disable the StateChecks that your master tells "CheckedBusOk"
