IC660BBA020系统备件
LIL OPC服务器i|ware PC操作员界面软件包括一个LIL OPC服务器，当连接到控制器时，该服务器可以：
使用在站中配置的回路的数量和类型自动填充其数据库。中使用的所有标记名
LIL OPC数据库将与本手册中列出的相同。
以太网OPC服务器
i|ware PC操作员界面软件是一个OPC客户端，可以连接到OPC服务器。以太网
使用开放式Modbus/TCP协议的OPC服务器可用于从单个或多个控制器获取数据，以及将数据发送到OPC客户端。
Modbus应用说明：有关使用Modbus的信息，请参阅应用文件AD353-108与控制器产品的通信。7.2站点数据车站包含一些与整个车站有关的数据，一些与单个回路有关。站点数据，可用通过网络，是站点功能块（STATN）配置的一部分，并映射到中的固定位置安装可选LIL板时，Modbus寄存器或线圈和固定通道/参数。循环数据（详见下一节）可与控制器“控制回路”或定序器“定序器回路”相关联通过选择操作员显示器定义：ODC“控制器操作员显示器”或ODS“操作员序列器显示”。
大部分可用的模拟数据有两种格式。
第一个是16位值，与以前的LIL一致
产品，实现与现有LIL系统的集成。此数据类型还提供Modbus主控器，无法处理32位浮点，一种从工作站获取数据的方法。
第二种是标准32位IEEE浮点格式，与站点中的实际数据一致。这些数据类型包含在两个连续的寄存器或参数中。
•使用Modbus时，LSW为第一，MSW为第二。
•使用LIL时，第一个参数包含MSW，第二个参数包含LSW。
•布尔值打包成16位字，供LIL使用，在使用Modbus时可在线圈中使用。
•字符串数据，格式为每个字2个ASCII字符，最左边的字符在最有效字节中，
包含标签、单位和消息信息的Modbus和LIL可用。
除以下情况外，大多数台站数据为“只读”：
SE（站点错误）参数，允许写入$0000以重置当前错误作为确认
•SSW（站状态字）参数，允许写入某些位（线圈）
•MLTP（Modbus回路趋势指针，包括在版本1.30固件中）参数
•AASEL（激活确认站错误日志，包括在版本1.30固件中）参数
•下文所述的其他项目
LIL OPC Server
The i|ware PC Operator Interface software includes an LIL OPC server that when connected to the controller can
auto populate its database with the number and type of loops configured in the station. All tag names used in the
LIL OPC database will be the same as listed in this manual.
Ethernet OPC Server
The i|ware PC Operator Interface software is an OPC Client and can be connected to an OPC server. An Ethernet
OPC server using the Open Modbus/TCP Protocol is available to obtain data from single or multiple controllers and
server the data to OPC clients.
Modbus Application Note: Refer to application document AD353-108 for information on using Modbus
communications with controller products. 7.2 STATION DATA
A station contains some data that pertains to the entire station and some to individual loops. Station data, available
over the network, is part of the station function block (STATN) configuration and is mapped to fixed locations in
Modbus registers or coils and fixed channel/parameters when the optional LIL board is installed. Loop data
(detailed in the next section) can be associated with a Controller “Control Loop” or a Sequencer “Sequencer Loop”
as defined by the selection of the operator display: ODC “Operator Display for Controller” or ODS “Operator
Display for Sequencer”.
Much of the analog data is available is two formats. The first is 16-bit values, scaled consistent with previous LIL
products, enabling integration into existing LIL systems. This data type also provides Modbus masters, unable to
handle 32-bit floating point, a method for obtaining data from the station.
The second is the standard 32-bit IEEE floating point format consistent with the actual data in the station. This data
type is contained in two consecutive registers or parameters.
• When using Modbus, the LSW is first and the MSW second.
• When using LIL, the first parameter contains the MSW and the second parameter the LSW.
• Boolean values are packed into 16-bit words for LIL use and are available in coils when using Modbus.
• String data, formatted as 2 ASCII characters per word with the left-most character in the most significant byte,
containing tag, units, and message information is available with Modbus and LIL.
Most Station data is ‘Read Only’ except for:
• SE (Station Error) parameter that allows a write of $0000 to reset the current error as an acknowledgment
• SSW (Station Status Word) parameter which allows writes to certain bits (coils)
• MLTP (Modbus Loop Trend Pointer, included in version 1.30 firmware) parameter
• AASEL (Active Acknowledged Station Error Log, included in version 1.30 firmware) parameter
• other items as noted below
