CERN is upgrading the LEP e+-e-collider for energies above the Z0particle by installing super-conducting cavities. The cryogenic system attached to these cavities is controlled by a distributed, industrial control system, having been the object of a tender. The issues relate to the software specification, the management of the contract, the installation and the gradual commissioning of the system. The experience with a fully farmed- out solution is reported. © 1994.
