1. A method for allocating subscriber addresses to bus subscribers in a bus-based control system for the automated control of a technical process, the method comprising the following steps: providing a plurality of bus subscribers which are connected to one another by means of a communication medium, assigning logical subscriber addresses to the bus subscribers, and verifying the assigned logical subscriber addresses, wherein the bus subscribers use a defined mathematical operation to calculate a common first check value which is compared with a second check value in order to verify the assigned logical subscriber addresses, wherein the mathematical operation begins with a defined starting value and comprises a number of operation steps which use a number of defined operands, wherein each of the subscriber addresses to be verified forms a different operand, and wherein each bus subscriber executes at least one operation step.
