描述
系統聯機前要進行組態(tài),即確定系統管理的I/O點數,輸入寄存器、保持寄存器數、通信端口數及其參數、I/O站的匹配及其調度方法、用戶占用的邏輯區(qū)大小,等等。組態(tài)一經確認,系統便按照一定的約束規(guī)則運行。重新組態(tài)時,按原組態(tài)的約定生成的程序將不能在新的組態(tài)下運行,否則會引起系統錯亂。因此,第一次組態(tài)時一定要慎重,I/O站、I/O點數,寄存器數、通道端口數、用戶存儲空間等均要留有余地,必須考慮到近期的發(fā)展。但是,I/O站、I/O點數、寄存器數、端口數等的設置,都要占用一定的內存,同時延長掃描時間,降低運行速度。因此,余量又不能留得太多。特別要引起注意的是運行中的系統一定不能重新組態(tài)。
產品廣泛應用于:電力、石油、礦井提升、港口、供熱、燃氣、供水、污水處理、冶金、造紙、紡織、化工、水利等現代化工業(yè)領域!
