Machines and beamlines controlled by VME industrial network are very popular in accelerator faculties [1, 2]. Recently new software technology, of which is internet/intranet, Java, Distributed calculation environment changes the control manner rapidly. A program based on DCOM  is composed to control of a variable included angle spherical grating monochromator beamline  at National Synchrotron Radiation Laboratory in China. The control computer with the DCOM program resident is connected to Intranet by LAN, from which the user-end operating computer sends driving beamline units!/ commands to the control computer. A web page coded in Java, published by the WWW service running in the control computer, is demonstrated how to use web browser to query the states of or to control the beamline units.
