| Abstract: | To design automat liquid sampler for GC, the solution with PLC is introduced. PLC is used to control several motors as well as communicate with its host PC bidirectionally. Requirement on precision is satisfied. Also the application of PLC can offer the system with extra reliability in industrial environment. Both the software and hardware architecture is discussed. The method to control motors is the key point. |
