	Several RF Superconductive LINAC projects are underway in different laboratories around the world, with various objectives such as research in physics, irradiation tests, production of radioisotopes for medical purposes. Superconducting operation of the accelerating cavities requires them to be maintained at cryogenic temperatures (2K - 4K) by the use of cryogenic fluids. This requires a complete cryogenic control system, including sensors, actuators, local controllers and PLCs. We describe the process by which the preliminary design of the cryogenic control system for the accelerator’s cryomodules and valve boxes may be built. It starts with the functional and performance requirements of the system, followed by the definition of use cases and the study of the necessary cryogenic instrumentation. This leads to a preliminary design of the architecture of the cryogenic control system using Siemens hardware, as well as cryogenic sequences describing standard phases of operation of the LINAC. We also discuss how to take advantage of the modularity of cryomodules for control system implementation and some recent developments in PLC simulation.
