In up - computer software design , aimed at realizing human - computer interface and data communication , the functions such as system interface design , data management , up - down computer communication are designed
3.
Secondly , five modules which include system general design , the coordinates extracting system , the coordinates data management , the automatic production of tables and the system interface design were mainly introduced . while the design process and algorithm realization of each module were discussed in detail
4.
With function module design method , the system interface design is completed ; by application of network function , the data is communicated to main - computer in order to retroactively supervisor product quality and to monitor local manufacture . through inspection of response of plc , the problems of dada efficacy and malfunction alarm in icc - plc communication are solved ; with adding symbol - bit , the exact conversion of receiving and sending data is realized
