FOXBORO 870ITEC-AYFNZ
870ITEC-AYFNZ控制系統(tǒng)的軟件主要包括系統(tǒng)軟件和用戶程序。系統(tǒng)軟件由PLC廠家固化在存儲(chǔ)器中，用于控制PLC的運(yùn)作。用戶程序由使用者編制錄入，保存在用戶存儲(chǔ)器中，用于控制外部對象的運(yùn)行。
1）、系統(tǒng)軟件
870ITEC-AYFNZ系統(tǒng)軟件包括系統(tǒng)管理程序、用戶指令解釋程序、標(biāo)準(zhǔn)程序模塊及系統(tǒng)調(diào)用。整個(gè)系統(tǒng)軟件是一個(gè)整體，它的質(zhì)量很大程度上影響了PLC的性能。通常情況下，進(jìn)一步改進(jìn)和完善系統(tǒng)軟件就可以在不增加任何設(shè)備條件下大大改善PLC的性能，使其功能越來越強(qiáng)。
2）用戶程序
870ITEC-AYFNZ的程序一般由三個(gè)部分構(gòu)成：用戶程序、數(shù)據(jù)塊和參數(shù)塊。用戶程序是必選項(xiàng)，數(shù)據(jù)塊和參數(shù)塊是可選部分。
用戶程序即應(yīng)用程序，870ITEC-AYFNZ是用戶針對具體控制對象編制的程序。PLC是通過在RUN方式下，循環(huán)掃描執(zhí)行用戶程序來完成控制任務(wù)的，用戶程序決定了一個(gè)控制系統(tǒng)的功能。一個(gè)完整的用戶程序應(yīng)當(dāng)包含一個(gè)主程序、若干子程序和若干中斷程序三大部分。
The software of PLC control system mainly includes system software and user program. The system software is solidified in the memory by the PLC manufacturer to control the operation of PLC. The user program is compiled and entered by the user and saved in the user memory to control the operation of external bs.870itec-ayfnz system software includes system management program, user instruction interpreter, standard program module and system call. The whole system software is a whole, and its quality affects the perbance of PLC to a great extent. Generally, further improvement and perfection of the system software can greatly improve the perbance of PLC without adding any equipment and make its function stronger and stronger.
The program of 870itec-ayfnz is generally composed of three parts: user program, data block and beter block. User program is required, and data block and beter block are optional parts.The user program is the application program, and 870itec-ayfnz is the program prepared by the user for the specific control b. PLC completes the control task by cyclic scanning and executing the user program in the run mode. The user program determines the function of a control system.A complete user program should include a main program, several subroutines and several interrupt programs.
