No PLC has ever been as chaotic as Schneider . The software alone is messy and messy. It is about to gather the Eight-Power Allied Forces. It makes the person who has just contacted Zhang Er monk confused, and it also brings extremes to the maintenance personnel of the factory. Great difficulty. In fact, this is determined by his special history. Schneider is a common name in Germany, just like our Xiaohong, Xiao Ming, and dog leftovers, everywhere in the street. Schneider is an investment company. PLCs are acquired in various ways, including the famous Modicon company, which is the Modicon company that produced the world’s first PLC 084, and the company of the inventor of PLC Dick Morley. Acquired by Schneider. Today, I will sort out the software of each series of Schneider PLC.

1、MODICON

The Quantuam Momentum series of US Modicon was acquired, using the software Concept.

2、TE

The Premieum Micro series of the US TE company acquired, using software PL7.
Both of these are American products of pure descent and are representatives of American PLCs. Now it has been integrated into a software Unity Pro. It mainly supports Quantuam Premieum M340 and M580 series PLCs. Because they are American products, the programming styles of Unity Pro and AB GE PLCs are very similar.
Unity Pro is mainly used in the EU industry, such as oil fields, electric power, mining, municipal and other large-scale engineering projects. As for Momentum and Micro, either stop production or slowly withdraw from the Chinese market, it is very rare. Unity Pro software is not supported, continue to use the original software.
As shown in the figure, the main control PLC Quantum series used in a subway control center uses hardware redundancy.
