| Abstract: | Based on the configuration software（IFIX） and PLC,an on-line inverse gas chromatograph control system with PVC resin filling the chromatograph column,VCM as probe,and N2 as carrier gas was designed to evaluate PVC desorption properties.The monitor system was composed of upper compute,the SIEMENS S7-200 PLC,gas chromatographic,communication module and on-site execution units.Visual Basic was used as development language to control the production process.Experiment result indicates that this system is easy to operate,stable and reliable in performance and it meets the design requirements. |
