ICS TRIPLEX 9852*4
ICS® Triplex® 過程安全產(chǎn)品的生命周期階段定義如下。所有 ICS Triplex 過程安全產(chǎn)品始終可以部分升級或完全遷移到最新的產(chǎn)品系列。ICS Triplex Legacy 產(chǎn)品生命周期進(jìn)程是在一個模塊一個模塊的基礎(chǔ)上決定的,具體取決于組件過時、市場需求和整體支持能力。羅克韋爾自動化的目標(biāo)是為從一個生命周期階段到下一個生命周期階段的任何過渡提供至少 12 個月的通知期。
但是在這一塊來看,其實我們設(shè)備在過去20年上一代高端控制器的能力控制下,它的處理速度是沒有任何問題的,可以完全滿足工藝需求的,更快的控制系統(tǒng)對于改善和提升工廠的運(yùn)營收益已經(jīng)很難體現(xiàn)價值了。就像在高速公路上跑,你跑到500邁沒有意義,因為對于穩(wěn)定可靠性來說,我們制造一個車能跑到200多邁就達(dá)到期望了,就夠用了,你再快的速度也用不上,反而帶來潛在危害。在這種情況下,我們一味的再去像過去的時候,去追求比一個高端處理器多快,這個已經(jīng)沒有意義了。但有一點(diǎn)跟以前一樣,它的穩(wěn)定可靠性,就像我為什么要開轎車,不去騎摩托車呢?它畢竟安全可靠性要好。
高端控制器現(xiàn)在來看,不是說看能帶多少點(diǎn),處理速度快到什么程度,因為這些發(fā)展到上一代的時候已經(jīng)不是事了,現(xiàn)在隨便拿一個中小型控制器,說帶點(diǎn)能力和處理速度達(dá)到大型控制器的水平也都沒太大差距。但是核心的東西就是它的安全性、穩(wěn)定可靠性,它的系統(tǒng)的通訊能力,因為過去大型PLC主要是做大系統(tǒng),大系統(tǒng)一定是有相互之間通訊,有協(xié)同的管理能力,與上位機(jī)通訊的能力、支持能力,這些能力都是判斷這個系統(tǒng)是高端控制系統(tǒng),還是中小型控制系統(tǒng)。
Examine the following control system P&ID showing the addition of flocculant (a chemical compound used in water treatment to help suspended solids clump together for easier removal by filtering and/or gravity clarification) and lime for pH balance. Flocculant is necessary to expedite the removal of impurities from the water, but some flocculation compounds have the unfortunate effect of decreasing the pH value of the water (turning it more acidic). If the water’s pH value is too low, the flocculant ironically loses its ability to function. Thus, lime (an alkaline substance – high pH value) must be added to the water to counter-act the flocculant’s effect on pH to ensure efficient flocculation. Both substances are powders in this water pre-treatment system, metered by variable-speed screw conveyors and carried to the mixing tank by belt-style conveyors:The control system shown in this P&ID consists of a pH analyzer (AT) transmitting a signal to a pH indicating controller (AIC), adjusting the speed of the lime screw conveyor. The flocculant screw conveyor speed is manually set by a hand indicating controller (HIC) – sometimes known as a manual loading station – adjusted when necessary by experienced water treatment operators who periodically monitor the effectiveness of flocculation in the system.
This simple feedback control system will work fine in steady-state conditions, but if the operator suddenly changes flocculant flow rate into the mixing vessel, there will be a temporary deviation of pH from setpoint before the pH controller is able to find the correct lime flow rate into the vessel to compensate for the change in flocculant flow. In other words, flocculant feed rate into the mixing tank is a load for which the pH control loop must compensate.
