P0924TR輸入輸出模塊
TO（跟蹤輸出）通常用于使用外部設備設置偏置的應用中偏置參數(shù)的位置（然后將B設置為0.0）。當需要使偏置塊的輸出跟蹤TV變量，外部設備被迫跟蹤。輸入E將等于TV-[A+（0.0）]，因此塊輸出O1的偏置將等于TV。在i|config中編輯包含偏置功能塊的配置，然后將其下載到在線控制器將忽略偏置參數(shù)值的變化，并繼續(xù)以預降負荷值運行。3.2.25 CIE_線圈輸入-以太網(wǎng)（V3.0）CIE_功能塊在以下情況下可用：
可選以太網(wǎng)通信板8是安裝在控制器中。它啟用控制器從其他站點獲取線圈數(shù)據(jù)以太網(wǎng)。
最多可提供32個CIE_塊。積木是按順序分配，控制器范圍，每個使用最多可從以下位置獲得16個線圈：Modbus設備。每個線圈分配給塊輸出C0–CF。
IP地址參數(shù)用于配置源Modbus設備的IP地址。
這個MB ADRES參數(shù)允許Modbus地址待配置。
當連接到其他西門子摩爾控制器，Modbus地址設置為1。在某些情況下，其他Modbus設備可能使用不同的地址，或者通過Modbus TCP/IP網(wǎng)關，Modbus網(wǎng)絡可能有多個設備，每個設備具有唯一的住址
START CL參數(shù)標識第一個線圈的位置。后續(xù)線圈（最多16個）可通過以下方式獲得：將CL參數(shù)的編號設置為大于1的值。數(shù)據(jù)類型參數(shù)啟用線圈讀數(shù)（Modbus功能代碼01）或輸入（Modbus功能碼02）。兩者處理相同，但線圈類型為：最常見的用法。UD速率參數(shù)配置塊請求數(shù)據(jù)的速率。這個P2P設置將以以太網(wǎng)塊中P2P速率參數(shù)設置的速率更新數(shù)據(jù)。Ct設置將在控制器的循環(huán)時間更新數(shù)據(jù)。
輸出QS指示接收數(shù)據(jù)的質量，當數(shù)據(jù)不好時，輸出QS將變高（1）。這通常是與由于通信故障或源的錯誤配置而無法接收數(shù)據(jù)相關。
CHR_功能塊提供10個段，可以：用于表征X輸入信號。個人通過輸入Xn、Yn和Xn+1來配置段，每個段的Yn+1點。所有Xn+1點必須為大于相關的Xn點。輸入X在工程單位和Y點應在表征器輸出所需的工程單位。
The TO (Tracked Output) is normally used in applications where an external device is being used to set a bias in
place of the BIAS parameter (B is then set to 0.0). When it is desired to have the output of the BIAS block track the
TV variable, the external device is forced to track TO. Input E will then equal TV- [A+(0.0)] and, therefore, the
BIAS block output O1 will equal TV.
When a configuration containing the BIAS function block is edited in i|config and then downloaded to an on-line
controller, the controller will ignore a change to the BIAS parameter value and continue to run with the predownload value. 3.2.25 CIE_- Coil Inputs - Ethernet (V3.0)
CIE_ function blocks are available when the
optional Ethernet communication board8
is
installed in the controller. It enables the controller
to obtain Coil data from other stations over the
Ethernet network.
Up to 32 CIE_ blocks are available. Blocks are
assigned in sequence, controller wide, with each
use. Up to 16 Coils can be obtained from a
Modbus device. Each Coil is assigned to block
outputs C0 – CF.
The IP ADRES parameter is used to configure the
IP address of the source Modbus device. The
MB ADRES parameter allows a Modbus address
to be configured. When connecting to other
Siemens MOORE controllers, the Modbus
address is set to 1. In some cases, other Modbus
devices may use a different address or when
going through a Modbus TCP/IP gateway a Modbus network may have multiple devices, each having a unique
address.
The START CL parameter identifies the location of the first Coil. Subsequent Coils, up to 16, can be obtained by
setting the NO OF CL parameter to a value greater than 1. The DATA TYP parameter enables reading of Coils
(Modbus Function Code 01) or Inputs (Modbus Function Code 02). Both are treated the same but the Coil type is
the most common usage. The UD RATE parameter configures the rate at which the block will request data. The
P2P setting will update the data at the rate set by the P2P RATE parameter in the ETHERNET block. The Ct
setting will update the data at the cycle time of the controller.
Output QS indicates the quality of the received data and will go high (1) when the data is bad. This is normally
associated with failure to receive data due to a communication failure or a misconfiguration of the source.
CHR_ function blocks provide 10 segments that can be
used to characterize the X input signal. Individual
segments are configured by entering the Xn, Yn and Xn+1,
Yn+1 points for each segment. All Xn+1 points must be
greater than the associated Xn points. Input X is in
engineering units and the Y points should be in the
engineering units desired for the characterizer output.
