要查看儀表的報(bào)警代碼，請(qǐng)?jiān)贛odbus字典中搜索“儀表報(bào)警”“儀表計(jì)算”一節(jié)。

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(shí)施的每個(gè)儀表運(yùn)行。此輸出功能塊
（OFB）可以以下列格式處理過程變量：

?浮點(diǎn)

?縮放整數(shù)

?4至20 ma（原始A/D）

注1：對(duì)于水（僅限液體），浮點(diǎn)數(shù)不可用。作為縮放整數(shù)，它必須是復(fù)制到元素1，并包含兩個(gè)小數(shù)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(diǎn)格式占用每個(gè)過程變量的兩個(gè)元素（32位）。對(duì)于例如，溫度必須從控制器中的浮點(diǎn)標(biāo)記復(fù)制到元素2

和輸出功能塊（OFB）的3。

注3a：溫度作為標(biāo)度整數(shù)必須復(fù)制到元素3，小數(shù)點(diǎn)后2位隱含的（1/100度）。例如，24.97°F的溫度必須復(fù)制為2497。元素2被忽略。

注3b：流動(dòng)壓力作為縮放整數(shù)必須復(fù)制到元件5，無小數(shù)點(diǎn)表示國(guó)際單位制（kPa），小數(shù)點(diǎn)后一位表示美國(guó)單位制（psi）。例如，一個(gè)5000 kPag的壓力必須復(fù)制為5000，259.7 psi的壓力必須復(fù)制為2597.元素4被忽略。

注3c：壓差作為一個(gè)標(biāo)度整數(shù)必須以2位小數(shù)復(fù)制到元件7水英寸的位置和千帕的3個(gè)位置（所選單位的1/100和1/1000）。對(duì)于例如，水溶液中37.52的DP必須復(fù)制為3752。元素6被忽略。

注3d：流量作為縮放整數(shù)必須復(fù)制到元素5，小數(shù)點(diǎn)后零位暗指的。元素6被忽略。要獲得所需的精度，請(qǐng)選擇適當(dāng)?shù)牧髁枯斎胙b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(shù)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(diǎn)格式可用。作為一個(gè)縮放整數(shù)必須以整數(shù)形式復(fù)制到元素11，單位為Hz，小數(shù)點(diǎn)后零位。對(duì)于例如，2574 Hz的頻率必須復(fù)制為2574。

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

?相對(duì)密度：小數(shù)點(diǎn)后四位。（1.0023 60F/60F必須輸入為10023）

?API：兩個(gè)隱含的小數(shù)位。（80.45°API必須輸入為8045）。

注5：對(duì)于4至20 mA格式，必須復(fù)制模擬輸入模塊的原始A/D計(jì)數(shù)作為OFB對(duì)奇數(shù)編號(hào)元素的整數(shù)（或表示水的元素1%）。將忽略偶數(shù)編號(hào)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 bat for each instrument run implemented through the AFC manager. This output function block
(OFB) process variables can be processed in the following bat:
? 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 b as 723. The module divides the value by 100.
Note 2: the floating-point bat 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 b of element 7 water inch and 3 bs 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 b device (instrument configuration b, main b characteristics panel)
Note 3e: the pulse frequency can be provided in proportional integer or 4 to 20 mA bat, which is only applicable to version 2.05 or higher; In version 2.04 or earlier, only floating point bat 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.
