以太網板支持通過以太網LAN上傳和下載控制器配置。對于例如，如果在圖1-2所示的本地客戶端上加載i|config圖形配置實用程序軟件，可以在客戶端上開發控制器配置，或從控制器上傳以進行編輯，然后下載到控制器。還可以從遠程服務器獲取數據，用于存檔和/或數據挖掘。圖1-2中的以太網Modbus網橋接受來自控制器的以太網數據命令，并且向地址1處的Modbus設備輸出等效Modbus命令。返回的Modbus數據被嵌入
由網橋在以太網分組中發送到請求控制器。
無論所選通信選項如何，顯示屏組件下側的RS232端口將使用Modbus通信。控制器硬件架構設計用于適應其他新興的現場總線技術。這包括需要較低功率以實現本質安全和較高速度的現場通信植物間網絡。
對于小型改裝應用，帶有操作員面板的Moore 353可替代簡單的單機
單回路控制器。它很容易升級，具有用于高級控制的額外I/O和通信選項策略和工廠網絡。

1.2功能塊
控制器軟件基于以前的LIL產品和西門子的成熟功能塊設計
支持IEC1131標準的APACS?產品。在許多情況下，控制器已通過只有現在最先進的技術才能提供這些功能。選擇功能塊在循環中使用。可以配置多個環路，每個環路可以
與操作員面板相關聯。某些塊在每個循環內使用一次（例如，自動/手動），其他的可以根據需要多次使用。一些值得注意的功能包括在
PID功能塊，一個可擴展的定序器，允許配置多達250個步驟和多達256個離散輸入和輸出。此外，圖形配置實用程序可用于設計梯形圖中的邏輯
簡圖將這些功能與同一控制器內的連續控制回路相結合，為小批量操作提供了良好的集成解決方案。
站級有幾個功能塊可用于配置站級參數，如車站地址和車站標簽名稱。功能塊包括時鐘塊（當RTC/CB選項
已包括板）和以太網塊（當安裝了以太網板和控制器時包含固件V2.4或更高版本）以配置諸如IP地址的參數。所有其他功能塊包括：
用于單個循環內的配置。在摩爾353中，通過以下方式配置控制實現：
首先創建一個循環，然后輸入一個唯一的循環標記名，并選擇在該循環中使用的功能塊。A.在Moore 353中可以配置多個回路，并且多種功能塊類型可用：將在下面的章節中描述。
The Ethernet board supports uploading and downloading of controller configurations over the Ethernet LAN. For
example, if i|config Graphical Configuration Utility software is loaded on the local client shown in Figure 1-2,
controller configurations can be developed on the client, or uploaded from the controller for editing, and then
downloaded to the controller. Data can also be acquired from remote servers for the purpose of archiving and/or
data mining. The Ethernet-Modbus Bridge in Figure 1-2 accepts an Ethernet data command from the controller and
outputs an equivalent Modbus command to a Modbus device at address 1. The returning Modbus data is embedded
by the bridge in an Ethernet packet to be sent to the requesting controller.
Regardless of the selected communication option, the RS232 port on the underside of the Display Assembly will
communicate using Modbus. Controller hardware architecture is designed to accommodate other emerging fieldbus
technologies. This includes field communications that require lower power for intrinsic safety and higher speed for
interplant networking.
For small retrofit applications, the Moore 353 with operator faceplate is a replacement for a simple stand-alone
single-loop controller. It is easily upgraded with additional I/O and communication options for advanced control
strategies and plant networking.
Often in this publication, reference is made to the labels on the controller to ensure that the controller being installed
has the correct power input, I/O, communication options, and approvals. This is particularly important when nonincendive requirements are present or a critical process is involved where a custom configuration or calibration has
been created. Label locations are shown in Figure 1-1 and typical labels are shown in Section 14 Model Designation
and Specifications.
1.2 FUNCTION BLOCKS
Controller software is built on proven function block designs from previous LIL products and from Siemens
APACS? products that support the IEC1131 standard. In many cases, the controller has been enhanced with
features only now possible with state of the art technology.
Function blocks are selected for use within a LOOP. Multiple loops can be configured, and each loop can be
associated with an operator faceplate. Certain blocks are used once within each loop (e.g. controller, setpoint,
auto/manual), others can be used as many times as needed. Some notable features include Auto Tuning within the
PID function blocks, an expandable Sequencer that allows configuration of up to 250 steps, and up to 256 discrete
inputs and outputs. In addition, the Graphical Configuration Utility can be used to design the logic in a ladder
diagram. Combining these features with continuous control loops within the same controller offers a wellintegrated solution for small batch operations.
Several function blocks are available at the station level for configuration of STATION level parameters, such as
the station address and station tag name. Function blocks include the CLOCK block (when the RTC/CB option
board has been included), and the ETHERNET block (when the Ethernet board has been installed and the controller
contains firmware V2.4 or higher) to configure parameters such as the IP address. All other function blocks are
used for configuration within an individual LOOP. Control implementations are configured in the Moore 353 by
first creating a loop, then entering a unique loop tag name and selecting function blocks for use within that loop. A
number of loops can be configured in the Moore 353 and a number of function block types are available as
described in the sections that follow.
