Prosoft MVI46-HART 多點主站網絡接口模塊

要查看儀表的報警代碼，請在Modbus字典中搜索“儀表報警”“儀表計算”一節。

儀表過程變量塊必須以配置的格式提供所有過程變量通過AFC管理器為實施的每個儀表運行。此輸出功能塊
（OFB）可以以下列格式處理過程變量：

?浮點

?縮放整數

?4至20 ma（原始A/D）

注1：對于水（僅限液體），浮點數不可用。作為縮放整數，它必須是復制到元素1，并包含兩個小數位。例如，水百分比值7.23必須為輸入為723。模塊將該值除以100。

注2：浮點格式占用每個過程變量的兩個元素（32位）。對于例如，溫度必須從控制器中的浮點標記復制到元素2

和輸出功能塊（OFB）的3。

注3a：溫度作為標度整數必須復制到元素3，小數點后2位隱含的（1/100度）。例如，24.97°F的溫度必須復制為2497。元素2被忽略。

注3b：流動壓力作為縮放整數必須復制到元件5，無小數點表示國際單位制（kPa），小數點后一位表示美國單位制（psi）。例如，一個5000 kPag的壓力必須復制為5000，259.7 psi的壓力必須復制為2597.元素4被忽略。

注3c：壓差作為一個標度整數必須以2位小數復制到元件7水英寸的位置和千帕的3個位置（所選單位的1/100和1/1000）。對于例如，水溶液中37.52的DP必須復制為3752。元素6被忽略。

注3d：流量作為縮放整數必須復制到元素5，小數點后零位暗指的。元素6被忽略。要獲得所需的精度，請選擇適當的流量輸入裝置（儀表配置窗口、主要輸入特性面板）

注3e：脈沖頻率可按比例整數或4至20 mA格式提供，僅適用于版本2.05或更高版本；在版本2.04或更低版本中，只有浮點格式可用。作為一個縮放整數必須以整數形式復制到元素11，單位為Hz，小數點后零位。對于例如，2574 Hz的頻率必須復制為2574。

注4：注意液體流量計的產品密度有三個選項，如果選擇“縮放整數”選項，則必須按如下方式將密度復制到元素9（元素8為忽略）：?Kg/m3：小數點后一位。（513.7 kg/m3必須輸入為5137）

?相對密度：小數點后四位。（1.0023 60F/60F必須輸入為10023）

?API：兩個隱含的小數位。（80.45°API必須輸入為8045）。

注5：對于4至20 mA格式，必須復制模擬輸入模塊的原始A/D計數作為OFB對奇數編號元素的整數（或表示水的元素1）。將忽略偶數編號的元素。

To view the alarm code of the instrument, search the Modbus dictionary for the section "instrument alarm" and "instrument calculation".
The instrument process variable block must provide all process variables in a configured format for each instrument run implemented through the AFC manager. This output function block
(OFB) process variables can be processed in the following format:
? floating-point
? Scaling integer
? 4 to 20 MA (original A / D)

Note 1: for water (liquid only), floating point numbers are not available. As a scaled integer, it must be copied to element 1 and contain two decimal places. For example, the water percentage value of 7.23 must be input as 723. The module divides the value by 100.
Note 2: the floating-point format occupies two elements (32 bits) of each process variable. For example, the temperature must be copied from the floating-point tag in the controller to element 2
And output function block (OFB).
Note 3A: as a scale integer, the temperature must be copied to element 3, which is implied by 2 digits after the decimal point (1 / 100 degrees). For example, the temperature of 24.97 ° f must be copied to 2497. Element 2 is ignored.
Note B: as a scaled integer, the flow pressure must be copied to element 5. No decimal point represents the international system of units (kPa), and one digit after the decimal point represents the U.S. system of units (PSI). For example, a 5000 kpag pressure must be copied to 5000259.7 psi pressure must be copied to 2597. Element 4 is ignored.
Note 3C: as a scaled integer, the differential pressure must be copied to the position of element 7 water inch and 3 positions of kPa (1 / 100 and 1 / 1000 of the selected units) with 2 decimal places. For example, DP of 37.52 in aqueous solution must be copied to 3752. Element 6 is ignored.
Note 3D: as a scaled integer, the flow must be copied to element 5, which is implied by the zero digit after the decimal point. Element 6 is ignored. To obtain the required accuracy, select the appropriate flow input device (instrument configuration window, main input characteristics panel)
Note 3e: the pulse frequency can be provided in proportional integer or 4 to 20 mA format, which is only applicable to version 2.05 or higher; In version 2.04 or earlier, only floating point format is available. As a scaled integer, it must be copied to element 11 as an integer, with the unit of Hz and zero after the decimal point. For example, a frequency of 2574 Hz must be copied to 2574.
