IC693BEM331觸控模塊
循環數據分為幾個類別。當使用LIL選項時，分組并不那么重要LIL數據的映射與以前使用全局和非全局數據的LIL產品一致。然而使用Modbus時，分組允許單個數據請求（最多60個字/寄存器或48個線圈）獲得
使用單個命令的類似數據。如果指定為控制器類型（即使用ODC塊）、定序器類型（即使用ODS塊）、模擬指示符顯示（即使用ODA塊）和模擬指示符顯示器（即，或離散指示器顯示（即使用奇數塊），或按鈕/開關操作（即使用ODP塊）。
a） 動態數據可能會在每次控制器掃描時改變值和/或未被識別為被數據改變
基礎變更位（線圈）。這類數據通常需要由工作站每隔幾秒鐘更新一次。
b） 變量數據定期更改。它通常與工作站上的在線操作相關，但可能僅限于：需要在較低的周期性基礎上或在指示數據庫更改時更新。
c） 靜態數據類似于變量數據，但更新要求較低。數據可能僅在以下情況下需要更新：
指示更改或驗證先前對參數所做的更改。
d） 字符串數據包含標記名、單位和消息。條件消息按發生順序堆疊。最新的9條活動條件消息可以：通過LIL或Modbus查看。
版本1.3包括45451處的配方消息。
版本2.2將配方消息移動到新位置
并將循環標記放置在配方消息的位置。1.讀取任何時間戳數據（即年、月、日、小時、分鐘、秒或采樣時間）將更新所有循環數據寄存器。同一塊內趨勢數據的附加數據讀取應僅請求數據，以便：
以獲得一組完整的時間同步數據。
2.趨勢數據從MLTP參數（寄存器40058）引用的循環中獲得。此參數可以：也可以寫入以改變循環。
3.參數NTTB將指示回路中可用的ATD模擬趨勢顯示塊的數量由MLTP指定。
4.未定義的數據（例如，未配置的輸入、時段站處于保持或斷電）由價值0美元。
5.實時時鐘數據需要隨附的可選RTC/CB（實時時鐘/配置備份）板
1999年7月和2.0或更高版本之后，MPU控制器固件7.3.13配置數據定序器回路
本頁上的Modbus寄存器或LIL參數指的是
先前由Modbus參數MSLCP（40048）或LIL參數LSLCP（7/1）定義的特定回路。對于
例如，讀取或寫入具有Modbus索引的循環中的PRSEQ塊的步驟1第0組輸入掩碼
對于3，將3寫入40048，然后讀取或寫入寄存器410001。
Loop data is grouped into several categories. The groupings are not as significant when using the LIL option as all
LIL data has been mapped consistent with previous LIL products using Global and Non-Global data. However,
when using Modbus, the groupings enable single data requests (up to 60 Words/Registers or 48 Coils) to obtain
similar data with a single command. The loop will have different data if assigned as a controller type (i.e. using the
ODC block), a sequencer type (i.e. using the ODS block), an Analog Indicator Display (i.e. using the ODA block),
or a Discrete Indicator Display (i.e. using the ODD block), or Pushbutton/Switch Operation (i.e. using the ODP
block).
a) Dynamic data may change value on each controller scan and/or is not identified as being changed by the data
base change bit (coil). This category of data usually needs to be updated by a workstation every few seconds.
b) Variable data changes periodically. It is usually associated with on-line operation at a workstation but may only
need to be updated on a lower periodic basis or when a data base change is indicated.
c) Static data is similar to variable data but has a lower update requirement. The data may only need updating when
a change is indicated or to verify a previous change made to a parameter.
d) String data contains tag names, units, and messages. Conditional messages are stacked in the order of occurrence. The 9 most recent active conditional messages can
be viewed over LIL or Modbus.
** Version 1.3 included the Recipe Message at 45451. Version 2.2 moved the Recipe Message to a new location
and placed the Loop Tag in place of the Recipe Message. 1. A read of any Time Stamp Data (i.e. Year, Month, Day, Hour, Minute, Second, or Sample Time) will update all
Loop data registers. Additional data reads of Trend data within the same block should only request data so as
to obtain a complete set of time synchronized data.
2. Trend data are obtained from the loop referenced by the MLTP parameter (register 40058). This parameter can
also be written to change the loop.
3. Parameter NTTB will indicate the number of ATD Analog Trend Display blocks that are available in the loop
specified by the MLTP.
4. Undefined data (e.g. unconfigured inputs, period station was in HOLD or powered down) are represented by a
value of $0.
5. Real time clock data requires the optional RTC/CB (Real Time Clock/Configuration Backup) board, shipped
after July 1999 and Version 2.0 or higher MPU Controller firmware 7.3.13 Configuration Data Sequencer Loop
The Modbus registers or LIL parameters on this page refer to configuration parameters of function blocks within a
specific loop previously defined by Modbus parameter MSLCP (40048) or LIL parameter LSLCP (7/1). For
example, to read or write the Step 1 Group 0 Input Mask for the PRSEQ block that is in a loop with a Modbus Index
of 3, write a 3 to 40048, then read or write to register 410001.
