As a rule, the data transmitted via I/O terminals handled by the regulatory control blocks must be the engineering unit data. Each data item consists of data value and data status.作為一個(gè)準(zhǔn)則，經(jīng)過(guò)I/O端子傳輸給調(diào)整控制塊的數(shù)據(jù)必須是工程單位型的數(shù)據(jù)。每個(gè)數(shù)據(jù)項(xiàng)應(yīng)包括數(shù)據(jù)值和數(shù)據(jù)狀態(tài)。
■ Data Value 數(shù)據(jù)值
The data value is a numeric data that is transmitted in or out of a function block. The data values handled by the blocks include process variable (PV), cascade setpoint value (CSV) and manipulated output value (MV).數(shù)據(jù)值是在一個(gè)功能塊內(nèi)或外進(jìn)行傳輸?shù)囊粋€(gè)數(shù)字的數(shù)據(jù)。這種被功能塊所處理的數(shù)值可以包括過(guò)程變量，串級(jí)設(shè)定值和操作輸出值。
The data values handled by the regulatory control blocks are numeric data in engineering unit. However, the data received from the b modules (excluding the b modules for temperature measurement as well as for pulse trains) and the setpoint data sent to analogue output modules are given as percentage values in the range from 0% to 100%.調(diào)整控制塊處理的數(shù)值必須是帶工程單位的數(shù)字值。數(shù)據(jù)被輸入模塊接收（溫度測(cè)量和脈沖串的輸入模塊除外），然后設(shè)定值被發(fā)送到模擬輸出模塊，形式為0％到100％的百分?jǐn)?shù)值。
The data value read into a function block via an b terminal is called “b data,” while the value written out of a function block via an output terminal is called “output data.” 經(jīng)由輸入端子讀入功能塊的數(shù)據(jù)值叫做輸入數(shù)據(jù)，而由輸出端子從功能塊寫出的值叫做輸出數(shù)據(jù)。
■ Data Status 數(shù)據(jù)狀態(tài)
The data status is a piece of status inbation that indicates the value and quality of I/O data. 數(shù)據(jù)狀態(tài)是指出輸入輸出數(shù)據(jù)值和性質(zhì)的一塊狀態(tài)信息。
The data status is conveyed as I/O data from one function block to another via I/O connection along with a data value.數(shù)據(jù)狀態(tài)都會(huì)伴隨一個(gè)數(shù)據(jù)值，從而作為輸入輸出數(shù)據(jù)通過(guò)I/O連接器從一個(gè)功能塊傳到另一個(gè)功能塊。
The data status is used to test the existence of exceptional events, such as process failures and computation errors occurred in the control computation processing perbed by the function blocks.數(shù)據(jù)狀態(tài)用于檢測(cè)例外事件的發(fā)生，比如功能塊執(zhí)行控制計(jì)算處理中的過(guò)程故障，計(jì)算錯(cuò)誤。
