UTILIZATION OF THE PORTABLE DATA ACQUISITION UNIT IN PROCESS CONTROL RELATED TASKS

This paper describes new portable data acquisition unit which was developed at our department for all tasks related to process control and identification. The device is designed with respect to possible battery operation which in conjunction with laptop computer enables process measurement in areas where power source is not available. Communication using standard RS232 serial interface makes it fully platform independent and thus suitable for connecting with any system, not only personal computer. Implemented ASCII- based communication protocol provides very effective way to communicate with number of software environments like Matlab/Simulink or ControlWeb, for instance. In order to improve development of new software applications with this device a support program library for Matlab/Simulink and Visual C++ was created
