Abstract：In this paper, it set forth how to design a long distributed tunnel stakeout and
controlling system by taking use of PLC and Configuration software 6.52.In detail set forth the
structure of system, designing of hardware and model of communication, use CAN
communication technique to carry out some PLC distributed communication between them,
implement communication between PLC and Host Computer in Enternet, the part of software
controlling adopts Component development technique，use these Components in Configuration software for shorten the time of development. This system has run for several months in Wuhan Yuemachang tunnel project, the running status is good.
Keywords: PLC; Configuration software; distributed communication; Component develop
