External Input & Application of Time Constant of Timer

YANG Hong-sheng,ZHU Jiu-yan(Department of Automaticity,Liaoning Petro-Chemical Vocational & Technical College,Jinzhou Liaoning 121001,China)  
In PLC,the time constant of timer is usually produced inside PLC.If the ON-OFF state of the input point is regarded as the digital quantity "0" and "1",and fit for different input points together with the corresponding ON-OFF states,then different "0" and "1"combinations will be formed and consequently different data will be generated.Taking the data as the time constant of timer,its external input can be realized.This paper takes the case of TVT-90 Programmable Controller machine,whose mainframe is the minitype C28P-CDR-AE of Japanese OMROM Company.With the control of simple simulated traffic lights,both the external input of the time constant of timer and the online time change of the time constant of timer are realized.
