Abstract In KISseismic instrumentation, the alarm end test unit are the operative framework of the system.There are so various nodes,including seismic alarm, fault monitoring, testing with no dump,etc. in the system that makes the control logic complex. To simplify system design and improve system reliability,the Programmable Logic Controller(PLC) is used for a implementation part of the alarm and calibration unit and achieve better application effect in this system.
