2. DCS workshop,march 10th P.Saturnini, F. Jouve Slow control trigger of the muon arm  Pvss courses(june 2002).  Implementation of pvss in our lab with a opc simulator (iconics opc server) from september 2002 up to now.  At the moment,we are waiting for the wiener opc server, it was foreseen for last september…… it is now foreseen for next september!!  Concerning our first full chamber test (called RPC1) next may at gif, we foresee to use the SLIC OPC for controling our low power supply. we’ll certainly need help for the control of the wiener pl500.
