MCC SCHNEIDER

Greetings to everyone who reads and supports my articles every day, today I want to write for the entire wonderful scientific community that lives on this great platform. This is the Motor Control Center also known as MCC for which we can use the following definition:

A Motor Control Center (MCC) is by definition, a board that feeds, controls and protects circuits whose load essentially consists of motors and uses starters (contactors and relays) as main control components. It consists of an arrangement or combination of several starters grouped in a general cabinet or board, of the self-supported type, to protect a certain group of motors, which also allows to achieve through its internal wiring the automation to perform a certain process..¹

The engines play a very important role in most industrial processes being those that act to maintain a variable in a given value, during my career I have had to install many types of systems but until now I had not had the opportunity to configure and automate an MCC, so I want to take the opportunity to share my experience with the community and when I get the desired results we will all celebrate together. To cover myself legally I want to make it clear that the information I intend to provide is based solely on the operation of the equipment without defining the process or disclose any other information belonging to the company for which I work or its client, in this sense I will only use the manufacturer's manuals and any information on the Internet that can serve as a reference respecting the parameters of copyright.

For this topic I want to address directly the motor control equipment TeSys-T from the manufacturer Schneider Electric, an intelligent motor management system. When associated with a short-circuit protection device and a contactor, the device provides complete monitoring, control and protection of electric motors..²

Among the most outstanding features we can mention that it provides primary protection, is an intelligent relay that can monitor electrical variables to provide excellent protection, can handle advanced communication protocols such as Modbus, Ethernet and others. It has an LTMCU unit that allows you to adjust the parameters to monitor, is easy to configure through an HMI device or through a PC using PowerSuit Software. ³

Before going on I think it is necessary at this point to define that Modbus is an industrial communication protocol for the transmission of information between different electronic equipment connected to the same bus. Many field devices use it to communicate with PLC's and SCADA's. ⁴ Within the protocol we can find MODBUS RTU and ModBus/TCP, in our case we will use the second that is compatible with our device TeSys T and the devices associated to the automation that we want to establish.

---

Each TeSys-T device must be configured within the network to be identified in the communication process, the configuration will be done through the PowerSuit software through a special Modbus RJ45 cable.

I'm not writing about something I've already done but about something I'm doing, it will take time to develop the system to its functional point so I think it will take me several articles to develop and describe all the devices along with their configurations, for now I leave this post and remain attentive to questions in the comments section. Greetings.
