Alarm Processing報(bào)警處理

Alarm processing performs various types of alarm check during input

processing,calculation processing and output processing in order to detect a

process error. When an error is detected, the alarm processing reflects the

detection of an alarm in the “alarm status" that is one of the data items of the

function block, and also notifies a message indicating the detection result to

the operation and monitoring.報(bào)警處理執(zhí)行輸入處理，計(jì)算處理及輸出處理過(guò)程中的各種報(bào)警檢查以便發(fā)現(xiàn)處理的錯(cuò)誤。當(dāng)一個(gè)錯(cuò)誤被發(fā)現(xiàn)，報(bào)警處理以報(bào)警狀態(tài)形式反映出檢測(cè)到的報(bào)警，報(bào)警狀態(tài)為功能塊的一個(gè)數(shù)據(jù)項(xiàng)，并且通知監(jiān)控一個(gè)指示檢測(cè)結(jié)果的信息。

Data Items數(shù)據(jù)項(xiàng)

A function block retains various data according to the type of the function block

in a database, which includes setup parameters and variable data that may be

referenced or set during the operation. Abbreviated names that are assigned

to these set parameters and variable data are generically called “data items."

For instance, the function block can perform calculation processing based on a

specific data item value and can reflect that processing result in another data

item.一個(gè)功能塊根據(jù)功能塊的類(lèi)型在數(shù)據(jù)庫(kù)中保持各種數(shù)據(jù)，包括在操作過(guò)程中可能會(huì)引用或設(shè)置的調(diào)整參數(shù)和變量。

The controls of the function block, such as“MAN"(manual) and “AUT" (auto),

and the “block mode"that indicates the output status are some of the data

items.功能塊的控制，例如手動(dòng)和自動(dòng)和指示輸出狀態(tài)的塊模式都是一些數(shù)據(jù)項(xiàng)。

Main data items are as follows:以下是主要的數(shù)據(jù)項(xiàng)

.Block mode (MODE)塊模式

.Block status(BSTS)塊狀態(tài)

·Alarm status(ALRM)報(bào)警狀態(tài)

Process variable (PV)過(guò)程變量

·Setpoint value (SV)設(shè)定值

·Manipulated output value (MV)輸出值

C2.I/O Connection I/O連接By performing the l/O connection, data can be exchanged between a function block and the connection destination according to the connection method當(dāng)執(zhí)行I/O連接時(shí)，數(shù)據(jù)依照連接方式能在功能塊和連接目標(biāo)間進(jìn)行交換。

Connection Destination of I/O ConnectionI/O連接的連接目標(biāo)With I/O connection, the destination and method of connection for each I/O terminalof a function block is specified. When the I/O connection is performed,process I/O,software I/O,communicationI/O, fieldbus I/O and other function blocks can bespecified as the connection destination of the function block's I/O terminal.I/O連接中，一個(gè)功能塊的的每個(gè)I/O端子的連接目標(biāo)和方式都是的。當(dāng)I/O連接執(zhí)行時(shí)，處理接口，軟件接口，通訊接口，總線(xiàn)接口及其他功能塊可被為功能塊的I/O端子的連接目標(biāo)。
