P0914SQ輸出卡件
幾個(gè)輸入可以控制ATD功能塊的操作。輸入E（啟用）可用于啟用趨勢(shì)高（1）或未配置時(shí)起作用。通過將E設(shè)置為低（0），可以禁用趨勢(shì)動(dòng)作。每次函數(shù)塊被啟用，將創(chuàng)建新的趨勢(shì)數(shù)據(jù)包。塊還包括參數(shù)overwrite，當(dāng)設(shè)置為YES時(shí)，將導(dǎo)致塊覆蓋舊數(shù)據(jù)（即圓形文件）。當(dāng)參數(shù)設(shè)置為“否”時(shí)，塊將在滿時(shí)停止趨勢(shì)分析，并保留數(shù)據(jù)直到重置。當(dāng)達(dá)到滿狀態(tài)時(shí)，輸出TF（趨勢(shì)滿）將變高（1）。此功能可用于啟用第二個(gè)ATD塊。AWE_功能塊在以下情況下可用：可選以太網(wǎng)通信板7安裝
在控制器中。它使控制器能夠?qū)懭耄和ㄟ^以太網(wǎng)。
多達(dá)32個(gè)AWE_塊可用。積木是按順序分配，控制器范圍，每個(gè)使用
數(shù)據(jù)可以寫為實(shí)數(shù)浮點(diǎn)數(shù)或者作為由數(shù)據(jù)配置的16位整數(shù)
典型參數(shù)。浮點(diǎn)數(shù)可以是選擇具有四個(gè)字節(jié)順序之一（字節(jié)ORD），其中1是最常見的（見表1在AIE塊描述下）。整數(shù)是從塊輸入S轉(zhuǎn)換而來，它是浮點(diǎn)數(shù)，按最小整數(shù)和最大值計(jì)算
使用范圍縮放信息的INT參數(shù)從中的源功能塊獲得帶有范圍指針輸入R的控制器。兩者無符號(hào)整數(shù)（Uint）和有符號(hào)整數(shù)（Sint）選項(xiàng)可用。請(qǐng)參見表格列表參數(shù)和默認(rèn)值如下。
IP地址參數(shù)用于配置的IP地址目標(biāo)Modbus設(shè)備
MB ADRES參數(shù)允許配置Modbus地址。當(dāng)連接到其他西門子摩爾控制器，Modbus地址設(shè)置為：1.在某些情況下，其他設(shè)備可能使用不同的地址或當(dāng)通過Modbus TCP/IP網(wǎng)關(guān)時(shí)網(wǎng)絡(luò)可以具有多個(gè)設(shè)備，每個(gè)設(shè)備具有唯一的地址。UD類型參數(shù)可以配置三個(gè)寫入更新選項(xiàng)。
1.oncE將向MB REG（Modbus寄存器）寫入一次。當(dāng)輸入值更改的值大于TRIG DB參數(shù)設(shè)置的值。此參數(shù)基于百分比設(shè)置由范圍指針輸入R確定的范圍。
2.P2P將以以太網(wǎng)塊中設(shè)置的控制器對(duì)等速率進(jìn)行更新。
3.Ct將在控制器的循環(huán)時(shí)間更新。
AWE_ function blocks are available when the optional Ethernet communication board7 is installed in the controller. It enables the controller to write analog data to other Modbus devices over the Ethernet network. Up to 32 AWE_ blocks are available. Blocks are assigned in sequence, controller wide, with each use. Data can be written as a real floating-point number or as a 16-bit integer as configured by the DATA TYP parameter. A Floating point number can be selected to have one of four byte orders (BYTE ORD) with 1 being the most common (see Table 1 under AIE block description). An integer is converted from the block input S, which is a floating point number, by the MIN INT & MAX INT parameters using the range scaling information obtained from the source function block in the controller with the range pointer input R. Both Unsigned Integer (Uint) & Signed Integer (Sint) options are available. See the table listing parameters and default values below. The IP ADRES parameter is used to configure the IP address of the destination 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 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. There are three write update options that can be configured by the UD TYPE parameter. 1. oncE will write once to the MB REG (Modbus Register). The controller will write when the input value changes by more than the value set with the TRIG DB parameter. This parameter is set based on a percentage of the range determined by the range pointer input R. 2. P2P will update at the controller peer to peer rate set in the ETHERNET block. 3. Ct will update at the cycle time of the controller.
