Эмуляция АСУ ТП: технические решения и практические аспекты реализации

Эта статья продолжает цикл воспоминаний разработчика тренажёрных комплексов. Несколько лет назад наша команда столкнулась с задачей создания эмулятора автоматизированной системы управления технологическим процессом (АСУ ТП) для одной из тепловых электростанций. Задача выглядела стандартной и несложной: воспроизвести логику контроллеров, разработать мнемосхемы и запустить модель. Однако реальность внесла свои коррективы. Исходных данных не хватало, сроки были крайне ограниченными, ресурсов недостаточно, а первая версия интерфейса HMI, созданная на собственном проверенном, но морально устаревшем инструменте проектирования, не соответствовала требуемым характеристикам производительности и масштабирования. Цель настоящей публикации — поделиться опытом разработки эмуляторов АСУ для учебных тренажёрных комплексов, рассмотреть типы симуляций, привести пример архитектуры подобного решения, коснуться используемых технологий и языков программирования, описать часто возникающие трудности и предложить способы их преодоления.

So Saint Patrick,

Maybe you can help me 🍀 where Saint Nick and Cupid failed. Still chasing job prospects, though one kind soul in YUL inquired, but we weren't a fit.

So maybe St. Paddy you could share some luck of the Irish with me or lead me to a pot of gold field of employers ☘️.

I know a variety of languages like #English, #French, #C, #Erlang, #Forth, #C#, #Java, #NodeJS, and poking at #Go. Have a history (if you ask) of experience that can bedazzle when applied.

So once more I launch yet another letter into the #fediverse seeking work.

I become even more grateful for #rust documentation whenever I have to deal with other languages'.

Today, I was looking at some #java code and trying to figure out what it was doing with a DecimalFormat object, which is part of the standard java.text. It has a method setMaximumIntegerDigits() which has apparently voluminous documentation. That is, there's a lot of it. But what happens if you have too many digits? Formatting 1234 with at most 3 digits just isn't going to work.

So, 90% of the runtime was wasted, because this fix was missing... 🤗
