I want to restrict the access to write specific variables in the data layer at a specific point of a plc program. In other words, I want to control whether someone can write a data layer variable or not within the plc, e.g. with an FB. Is this possible and how?

Hello,
it's not possible to restrict the access of data layer variables by the PLC.
You can restrict the access, user depended, by using scopes, but scopes can't be changed by the PLC.
