IC693BEM331触控模块
循环数据分为几个类别。当使用LIL选项时，分组并不那么重要LIL数据的映射与以前使用全局和非全局数据的LIL产品一致。然而使用Modbus时，分组允许单个数据请求（最多60个字/寄存器或48个线圈）获得
使用单个命令的类似数据。如果指定为控制器类型（即使用ODC块）、定序器类型（即使用ODS块）、模拟指示符显示（即使用ODA块）和模拟指示符显示器（即，或离散指示器显示（即使用奇数块），或按钮/开关操作（即使用ODP块）。
a） 动态数据可能会在每次控制器扫描时改变值和/或未被识别为被数据改变
基础变更位（线圈）。这类数据通常需要由工作站每隔几秒钟更新一次。
b） 变量数据定期更改。它通常与工作站上的在线操作相关，但可能仅限于：需要在较低的周期性基础上或在指示数据库更改时更新。
c） 静态数据类似于变量数据，但更新要求较低。数据可能仅在以下情况下需要更新：
指示更改或验证先前对参数所做的更改。
d） 字符串数据包含标记名、单位和消息。条件消息按发生顺序堆叠。最新的9条活动条件消息可以：通过LIL或Modbus查看。
版本1.3包括45451处的配方消息。
版本2.2将配方消息移动到新位置
并将循环标记放置在配方消息的位置。1.读取任何时间戳数据（即年、月、日、小时、分钟、秒或采样时间）将更新所有循环数据寄存器。同一块内趋势数据的附加数据读取应仅请求数据，以便：
以获得一组完整的时间同步数据。
2.趋势数据从MLTP参数（寄存器40058）引用的循环中获得。此参数可以：也可以写入以改变循环。
3.参数NTTB将指示回路中可用的ATD模拟趋势显示块的数量由MLTP指定。
4.未定义的数据（例如，未配置的输入、时段站处于保持或断电）由价值0美元。
5.实时时钟数据需要随附的可选RTC/CB（实时时钟/配置备份）板
1999年7月和2.0或更高版本之后，MPU控制器固件7.3.13配置数据定序器回路
本页上的Modbus寄存器或LIL参数指的是
先前由Modbus参数MSLCP（40048）或LIL参数LSLCP（7/1）定义的特定回路。对于
例如，读取或写入具有Modbus索引的循环中的PRSEQ块的步骤1第0组输入掩码
对于3，将3写入40048，然后读取或写入寄存器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.
