? Watch dog Timer
In order to detect the failure of Exasmoc controller or Exasmoc station, a watchdog timer function is provided. Exasmoc controller periodically sets a watchdog timer flag to the control station of DCS. The control station resets the flag every time when it is set. If Exasmoc controller cannot set this flag within a fixed interval then the control station recognizes the Exasmoc has failed, and the base controller (local loop) in control station will be switched from REMOTE to LOCAL mode.
This function is effective in all type of Yokogawa DCS mentioned in this manual. It might be also supported for other vendor DCS, provided it could handle this flag.
? User Defined Calculation (R3.06)
Apart from the Exasmoc controller standard function, Exasmoc Kernel collect input data using OPC interface, execute the define calculation and output the result.
Definition of Input tag, output tag and the calculation logic definition are done using PCTP: SMOCPro function. It is also possible to send the calculation result to process output or other DCS tags.
? 看門狗計時器
為了檢測Exasmoc控制器和Exasmoc站的故障,系統提供了看門狗計時器功能。Exasmoc控制器定期向DCS的控制站寫入看門狗計時器標簽。在寫入時,控制站中該標簽復位。如果在固定的時間間隔內Exasmoc控制器無法寫入此標簽,則控制臺會識別出Exasmoc斷線,控制臺中的基礎控制器(本地回路)將從REMOTE切換到LOCAL模式。
此功能在本手冊中提到的所有類型的橫河電機DCS中均有效。其他供應商DCS也可能支持,只要它可以處理此標簽。
? 用戶定義的計算(R3.06)
除了Exasmoc控制器標準功能外,Exasmoc Kernel采用OPC接口采集輸入數據,執行定義計算并輸出結果。
使用PCTP:SMOCPro功能來完成輸入位號,輸出位號和計算邏輯的定義。也可以將計算結果發送到過程輸出或其他DCS位號。

Preface
This document covers the operation aspects of Exasmoc online multivariable, model predictive and optimizing controller software integrated with the user’s DCS. The operational instructions are meant only for operating Exasmoc for the process plants. It is assumed that the user’s DCS and process plant is in operation. It is also assumed that Exasmoc application is running along with the operation displays.
Intended Readership
This manual is intended for use by plant operator and process engineer who are actually operating the plant and responsible to implement Exasmoc an online multivariable, model predictive and optimizing controller for their process. A good knowledge and experience of operating plant through DCS is essential. A basic knowledge of Advanced Process Control and Windows based system is also required.

前言
本文檔介紹了與用戶DCS集成的Exasmoc在線多變量,模型預測和優化控制器軟件的操作說明。操作說明僅適用于為工廠流程運行Exasmoc。 假設用戶的DCS和工廠流程正在運行。 還假設Exasmoc應用程序隨操作一起運行顯示。
面向讀者
本手冊旨在由實際操作工廠的工廠操作員和負責為其過程實施Exasmoc在線多變量,模型預測和優化控制器的過程工程師使用。 擁有良好的DCS運行,工廠知識和經驗是至關重要的。與此同時還需要先進過程控制和基于Windows系統的基礎知識。
