check variables while write before excepting in the PLC
I have tried to publish variables to the datalayer from the PLC and it works just fine👍. But I am looking for a functionality in the PLC which is similar to the "onWrite" function in the SDK for C/C++. When a user tries to write a value to the datalyer I want to make some sanity checks before I accept the new value in the PLC. Is it possible to solve somehow in the PLC?
