    "abstract": "As an accelerator control system survives over several years, it is often the\ncase that new subsystems are introduced into the original control system. The\ncontrol system for the KEK electron/positron injector-linac has been using Unix\nworkstations and VME computers since 1993. During the eight-year operation, we\nextended the system by introducing a) Windows PCs, b) PLC controllers with a\nnetwork interface, and c) web servers based on modern information technology.\nAlthough such new subsystems are essential to improve control functionalities,\nthey often cause communication problems with the original control system. We\ndiscuss the experienced problems, and present our solutions for them.",
