1.2.1回路功能塊類型兩個MPU控制器板上都提供了本地I/O功能塊
以及I/O擴展器板。這些塊可以在任何循環(huán)中使用，但作為固定資源是消耗性的。在循環(huán)中使用時，唯一塊
名稱變成＜loop＞<塊>（例如，用于模擬輸入1的TC2053.AIN1用于循環(huán)TC2053）?？梢赃x擇固定回路功能塊用于每個配置回路，并包括以下功能塊：定義循環(huán)的主要功能。操作員顯示功能塊（例如：?？刂破鞯腛DC操作員顯示）定義了循環(huán)類型、函數(shù)本地面板以及來自遠程工作站。單個控制器功能塊可從中選擇：
五個可用選項之一（ID、ON_OFF、PD、PIDAG和PID）
環(huán)在循環(huán)中使用時，唯一塊名將變?yōu)?lt;loop><block>（例如，用于回路中使用的PID控制器的TC2053.PIDTC2053）。
算術功能塊也稱為循環(huán)功能塊并且可以在每個循環(huán)中根據(jù)需要使用任意次數(shù)
塊的每次使用是：
在每個內(nèi)自動分配一個唯一的名稱（即MATH01、MATH02）循環(huán)，使唯一的塊名變?yōu)椋糽oop＞<塊>（例如：。TC2053.MATH01）。邏輯功能塊也被指定為循環(huán)功能塊，以及可以在每個循環(huán)中根據(jù)需要使用多次。塊的每次使用是：在每個文件中自動分配一個唯一的名稱（即AND01和02）
循環(huán)，使唯一的塊名變?yōu)椋糽oop＞<塊>（例如：。TC2053和01）。
通用功能塊也被指定為循環(huán)功能并且包括不屬于算術或邏輯類別的塊。
這些可以根據(jù)需要多次使用，每次使用都將自動在每個循環(huán)中分配一個唯一的名稱（例如HLD01、HLD02），以便唯一的塊名變?yōu)椋糽oop＞<塊>（如TC2053.HLD01）。
遠程I/O總線功能塊可根據(jù)需要在每個回路中使用（當安裝LonWorks選項時），以：提供一種發(fā)送和接收模擬和離散數(shù)據(jù)的方法：并通過遠程I/O數(shù)字總線從遠程設備接收。每次使用將在中自動分配一個唯一的名稱（如AIP01、AOP01）站，以便唯一的塊名變?yōu)椋糽oop＞<塊>（例如：。用于模擬輸入的TC2053.AIP01-lev_Percent用于回路TC2053）。這個站內(nèi)使用的第二個AIP塊將被分配為AIP02，即使在不同的環(huán)路，以便遠程I/O塊在工作站內(nèi)具有唯一的名稱。這將啟用唯一名稱用于LON網(wǎng)絡上的站變量。
1.2.1 LOOP Function Block Types
Local I/O Function Blocks are provided on both the MPU Controller Board
and the I/O Expander Board. These blocks can be used in any LOOP, but as
fixed resources are expendable. When used within a loop, the unique block
name becomes <loop>.<block> (e.g. TC2053.AIN1 for Analog Input 1 used in
loop TC2053). Fixed Loop Function Blocks can be selected for use within each configured LOOP and include those blocks which
define the major functions of a loop. The operator display function block (e.g.
ODC Operator Display for Controllers) defines the loop type, the function of
the local faceplate as well as the processing of commands coming from a
remote workstation. A single controller function block can be selected from
one of five available choices (ID, ON_OFF, PD, PIDAG, & PID) within each
loop. When used within a loop the unique block name becomes
<loop>.<block> (e.g. TC2053.PID for the PID controller used in loop
TC2053).
Arithmetic Function Blocks are also designated as LOOP function blocks
and can be used as many times as needed in each loop. Each use of a block is
automatically assigned a unique name (i.e. MATH01, MATH02) within each
loop so that the unique block name becomes <loop>.<block> (e.g.
TC2053.MATH01).
Logic Function Blocks are also designated as LOOP function blocks and
can be used as many times as needed in each loop. Each use of a block is
automatically assigned a unique name (i.e. AND01, AND02) within each
loop so that the unique block name becomes <loop>.<block> (e.g.
TC2053.AND01).
General Purpose Function Blocks are also designated as LOOP function
blocks and include blocks that do not fall into the arithmetic or logic categories.
These can be used as many times as needed and each use will automatically be
assigned a unique name (e.g. HLD01, HLD02) within each loop so that the
unique block name becomes <loop>.<block> (e.g. TC2053.HLD01).
Remote I/O Bus Function Blocks can be used as needed in each LOOP (when the LonWorks option is installed) to
provide a method for sending and receiving both analog and discrete data to
and from remote devices over the remote I/O digital bus. Each use will
automatically be assigned a unique name (e.g. AIP01, AOP01) within the
station so that the unique block name becomes <loop>.<block> (e.g.
TC2053.AIP01 for Analog Input-lev_Percent used in loop TC2053). The
second AIP block used within the station will be assigned AIP02 even if in a
different loop so that the remote I/O blocks have unique names within the station. This will enable unique names
for station variables on the LON network.
