Mai nly the se two rel atively cheap a nd y ou can m eet the ol dfashioned, simpl e (or simpl e) industrial e qui pment. S o he can see them now, however t hese two contr ol modes (relay and di screte el ectronic circuits) are the se fatal flaws: (1) cannot a dapt t o the plex logic control, (2) only for the curre nt project, t he la ck of patibility a nd (3) not reforming the sy stem with e qui pment impr ovements. S pring for t he development of China39。s modern i ndustrial a utomation technology the substantia l increase i n the l evel of industrial aut omation, pleted t he perfect relay of the puter too much. In terms of controlli ng the puter showed his tw o great adva ntages: (1) ea ch of the har dware can be installed on one or more mi cropr oce ssors。 (2) the official desig ner of the software writi ng content contr ol is all a bout. Now in several ways in t he context of industrial a utomation ca n often be se en i n three ways: (1) Programmable Logical Controller (referred to as IPC)。 (2) Distributed Control System (DCS for short), and (3) the Programmable Logi cal Controller (PLC for short). .2 PLC a nd the IPC and DCS contrast contrast 1, each of the t hree technologi es of origi ns a nd development requirement s for fast data processing makes it inve nted t he pute r. The men br oug ht in terms of har dware there, using a hig h level of standar dization, ca n use m ore patibility tools, i s a rich software re sour ces, especially t he ne ed for immedia cy in operational systems. So the puter can effectively control i s used to control and meet its spee d, on the virtual m odel , realtime a nd i n putational re quirement s.
