第二種是標(biāo)準(zhǔn)32位IEEE浮點(diǎn)格式，與站點(diǎn)中的實(shí)際數(shù)據(jù)一致。這些數(shù)據(jù)類型包含在兩個(gè)連續(xù)的寄存器或參數(shù)中。
?使用Modbus時(shí)，LSW為第一，MSW為第二。

除以下情況外，大多數(shù)臺(tái)站數(shù)據(jù)為“只讀”：

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
