The RILIS laser ion source is one of the central components of the ISOLDE on-line isotope production facility. A record of about 2500 hours of on-line operation for the year 2011 shows the major importance and high demand for RILIS which provides radioactive ion beams of various elements with the highest efficiency and unmatched isobaric purity. The RILIS is currently operated 24/7 with the operators continuously present to control and possibly correct the crucial laser parameters, i.e. wavelength, output powers and beam positions of all individual lasers in use. Moreover, the operator acts as contact person for the ISOLDE user to inform about its current status. Deploying a widely automated, network-based monitoring and control software will not only enable manpower to devote their time to system improvement rather than supervision but also greatly improve health issues and work safety as stay in areas with increased levels of radiation exposition will be significantly reduced. The on-going software and hardware development covers the four key aspects: Machine protection, monitoring of beam parameters, automated correction and a RILIS status display for the users. The concept and the status of implementation are presented.
