1.2功能块
控制器软件基于以前的LIL产品和西门子的成熟功能块设计
支持IEC1131标准的APACS®产品。在许多情况下，控制器已通过只有现在最先进的技术才能提供这些功能。选择功能块在循环中使用。可以配置多个环路，每个环路可以
与操作员面板相关联。某些块在每个循环内使用一次（例如，自动/手动），其他的可以根据需要多次使用。一些值得注意的功能包括在
PID功能块，一个可扩展的定序器，允许配置多达250个步骤和多达256个离散输入和输出。此外，图形配置实用程序可用于设计梯形图中的逻辑
简图将这些功能与同一控制器内的连续控制回路相结合，为小批量操作提供了良好的集成解决方案。
站级有几个功能块可用于配置站级参数，如车站地址和车站标签名称。功能块包括时钟块（当RTC/CB选项

用于单个循环内的配置。在摩尔353中，通过以下方式配置控制实现：
首先创建一个循环，然后输入一个唯一的循环标记名，并选择在该循环中使用的功能块。A.在Moore 353中可以配置多个回路，并且多种功能块类型可用：将在下面的章节中描述。
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.
