The invention claimed is: 1. A particle therapy device comprising: an accelerator; a particle beam delivery unit operable with the accelerator, the particle beam delivery unit operable to deliver particles to at least two irradiation positions; and a control system configured to monitor the particles along a particle beam path, the control system comprising an assignment unit, at least one control unit disposed at one of the at least two irradiation positions and an accelerator control unit, wherein the at least one control unit is configured to emit a request signal that requests a particle beam for an irradiation procedure, wherein the assignment unit is configured to assign the particle beam path to the requesting irradiation position, and is connected to configurable elements that direct the beam path, wherein only those configurable elements that are required for the beam path are selectively activated, and wherein the accelerator control unit is configured to emit configuration parameters to the configurable elements, the assignment unit configured as a fail-safe control system such that the assignment unit sends an activation signal to the configurable elements of the beam path when setting up the particle beam path, the activation signal separate from the emission of configuration parameters from the accelerator control, the activation signal being present during the implementation of the configuration parameters and allowing the implementation of the configuration parameters. 2. The particle therapy device as claimed in claim 1, wherein the control unit is operable to transfer data from a treatment plan. 3. The particle therapy device as claimed in claim 2, wherein the control unit is operable to trigger the activation signal that enables particle beam delivery at the requesting irradiation position. 4. The particle therapy device as claimed in claim 1, wherein the control unit is connected to an input of the assignment unit via a first permanently assigned signal connection, so that the presence of the request signal at the signal input unambiguously specifies the requesting irradiation position. 5. The particle therapy device as claimed in claim 1, wherein the assignment unit is operable to check an availability of the particle beam. 6. The particle therapy device as claimed in claim 1, wherein the assignment unit is operable to store a data table comprising the possible beam paths. 7. The particle therapy device as claimed in claim 1, wherein the accelerator control unit is operable to control the configuration of the configurable elements for the requested beam delivery. 8. The particle therapy device as claimed in claim 1, further comprising a permanently assigned signal connection from the assignment unit to the control unit, the signal connection being operable to transfer a confirmation signal between the assignment unit and the control unit of the requesting irradiation position. 9. The particle therapy device as claimed in claim 8, wherein the signal connections is a direct hardware connection. 10. The particle therapy device as claimed in claims 1, wherein at least two control units are individually connected, each via a permanently assigned signal connection and each to at least one output of the assignment unit. 11. The particle therapy device as claimed in claim 1, wherein the accelerator control unit and the at least one control unit are connected to a data bus system that is operable to exchange parameters of the particle beam, parameters of the accelerator and particle beam delivery unit that are specified by the control system with reference to a therapy schedule that forms the basis of the irradiation procedure, or both. 12. The particle therapy device as claimed in claim 1, wherein at least one of the at least two irradiation positions is a treatment position at which a patient is irradiated with the particles. 13. The particle therapy device as claimed in claim 1, wherein at least one of the at least two irradiation positions is a test position that is operable for checking parameters that characterize the particle irradiation. 14. A method for forming a beam path for an irradiation procedure in a particle therapy device which includes an accelerator and particle beam delivery unit operable to deliver particles to at least two irradiation positions and includes a control system operable to monitor and direct the particles along a particle beam path, wherein the control system comprises an assignment unit, a control unit arranged at each of the at least two irradiation positions and an accelerator control unit, the method comprising: initiating the irradiation procedure by communication between a control unit and the assignment unit, wherein a beam request signal and, following an assignment of the particle beam to the requesting irradiation position, a confirmation signal confirming the request are exchanged, transferring configuration parameters from the accelerator control unit to configurable elements of the accelerator and a beam transport unit, wherein the assigned control unit transfers information about the irradiation procedure to be carried out to the accelerator control unit, and activating the required elements specified by an activation signal from the assignment unit, when setting up the particle beam path, separately from the transferring, and implementing configuration parameters transferred from the accelerator control unit when the activation signal is present. 15. The method as claimed in claim 14, wherein activating the required elements take place concurrently with the transferring of configuration parameters. 16. The method as claimed in claim 15, wherein a "beam on" signal is transferred to the assignment unit during the initiating of the irradiation procedure, wherein the presence of the "beam on" signal in the assignment unit is a prerequisite for the execution of transferring of configuration parameters. 17. The method as claimed in claim 14, further comprising transporting particles along the formed beam path for irradiating in accordance with the irradiation procedure. 18. The particle therapy device as claimed in claim 1, further comprising a data bus system that is operable to transfer a confirmation signal between the assignment unit and the control unit of the irradiation position. 19. The particle therapy device as claimed in claim 1, further comprising an individual signal line connected between the control unit and the assignment unit. 20. The method as claimed in claim 14 wherein activating comprises authorizing operation of the required elements to act on a later received confirmation to deliver the particles. 21.
