As an accelerator control system survives over several years, it is often the case that new subsystems are introduced into the original control system. The control system for the KEK electron/positron injector has been using Unix workstations as device servers, and VME computers as front-end interfaces [1]. During the eight-year operation of this system, we have extended the system by introducing a) Windows-based system, b) PLC controllers with network interface, and c) web servers based on the modern information technology. Such new subsystems are essential to increase control functionalities, however, they always arise a control consistency problem in total. In other words, they always bring communication problems with the original control system. In this report, we discuss the problems we have experienced, and present our solutions for them.
