IC660BBA020系統(tǒng)備件
LIL OPC服務器i|ware PC操作員界面軟件包括一個LIL OPC服務器，當連接到控制器時，該服務器可以：
使用在站中配置的回路的數量和類型自動填充其數據庫。中使用的所有標記名
LIL OPC數據庫將與本手冊中列出的相同。
以太網OPC服務器
i|ware PC操作員界面軟件是一個OPC客戶端，可以連接到OPC服務器。以太網
使用開放式Modbus/TCP協(xié)議的OPC服務器可用于從單個或多個控制器獲取數據，以及將數據發(fā)送到OPC客戶端。
Modbus應用說明：有關使用Modbus的信息，請參閱應用文件AD353-108與控制器產品的通信。7.2站點數據車站包含一些與整個車站有關的數據，一些與單個回路有關。站點數據，可用通過網絡，是站點功能塊（STATN）配置的一部分，并映射到中的固定位置安裝可選LIL板時，Modbus寄存器或線圈和固定通道/參數。循環(huán)數據（詳見下一節(jié)）可與控制器“控制回路”或定序器“定序器回路”相關聯(lián)通過選擇操作員顯示器定義：ODC“控制器操作員顯示器”或ODS“操作員序列器顯示”。
大部分可用的模擬數據有兩種格式。
第一個是16位值，與以前的LIL一致
產品，實現與現有LIL系統(tǒng)的集成。此數據類型還提供Modbus主控器，無法處理32位浮點，一種從工作站獲取數據的方法。
第二種是標準32位IEEE浮點格式，與站點中的實際數據一致。這些數據類型包含在兩個連續(xù)的寄存器或參數中。
?使用Modbus時，LSW為第一，MSW為第二。
?使用LIL時，第一個參數包含MSW，第二個參數包含LSW。
?布爾值打包成16位字，供LIL使用，在使用Modbus時可在線圈中使用。
?字符串數據，格式為每個字2個ASCII字符，最左邊的字符在最有效字節(jié)中，
包含標簽、單位和消息信息的Modbus和LIL可用。
除以下情況外，大多數臺站數據為“只讀”：
SE（站點錯誤）參數，允許寫入$0000以重置當前錯誤作為確認
?SSW（站狀態(tài)字）參數，允許寫入某些位（線圈）
?MLTP（Modbus回路趨勢指針，包括在版本1.30固件中）參數
?AASEL（激活確認站錯誤日志，包括在版本1.30固件中）參數
?下文所述的其他項目
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
