SOFTWARE PROCESSING SYSTEM FOR DIGITAL FOR DIGITAL INSTRUMENTATION SYSTEM COMMUNICATION UNIT

摘要

PURPOSE:To simplify the use of a communication function and to improve the application by simplifying the initial setting in the communication processing and revising and adding freely the designation of a text length in on-line communication and of the expression form of CRC processing and to each data when the operation monitor is implemented by the process in a host computer system. CONSTITUTION:A reception task 1 receives a sent text and when an analysis section is designated with an in-text command code, the analysis section executes setting 8 to a sub command management table 5 and when the execution is finished, the result is stored in a reception text storage area 2 and the processing is requested to a control processing task 3. The control processing task 3 references a data via an instrumentation specific communication task 4 from control monitors 34, 36, executes the edit processing of a transmission text and processes such as data expression and test length. After the text is stored in a transmission text storage area, the transmission task 7 references (9) the sub command management table 5 similarly to the case with the control processing task 3, the addition of CRC processing or the like is executed and the transmission processing is executed. Thus, the operability of communication, the operation, the reliability and the maintenability are improved.
