Hello,

I'm working on a program that I would like to be a master program for several devices, so its needed to have a dynamic hardware configuration...
My hardware:
see image...

The objective is to activate or deactivate my EtherCAT masters depending on a single variable...
As example this variable will be an INT received over OpcUa. and it has 3 values 0, 1 or 2...
IF 0 THEN
Ethercat_master1 is active and the others deactivated
ELSIF 1 THEN
Ethercat_master2 is active and the others deactivated
ELSIF 1 THEN
Ethercat_master3 is active and the others deactivated
END_IF

Do you know a way to achieve this... currently I was working with the IODrvEtherCATDriver lib but I cannot find the right solution to this problem. Because whenever there in an hardware error (A master that isn´t there) I cannot execute my program.

Has somebody any experience with this kind of applications?

Best regards
Alebrije

Hello, I suspect it can be reconfigured:
