What is the purpose of the three-phase main device with neutral CcM4?
The three-phase main device with neutral CcM4 is one of the devices of the Smart Control CcM family, which is used to measure electrical parameters (voltage, current, energy, harmonic distortion, etc.) in three-phase installations with neutral.
The CcM family is composed of a set of devices whose objectives are energy efficiency, submetering and/or monitoring of electrical parameters in the switchboards of single-phase and three-phase installations, preferably housed in circuit breakers or differential switches to obtain multiple measurements at multiple points and be physically linked to each other by means of an RS-485 cable in a submetering design.
How does the three-phase main device with neutral CcM4 work?
Specifically, the three-phase main device with neutral CcM4 is part of the devices of the family of submetering energy meters known as "main" (CcM4, CcM2 and CcM2-W), since they have the dual function of acting as slaves of the general master (PLC or Windows/Linux PC, or CcMaster) on the main bus, and at the same time they can act as masters on the secondary bus commanding other devices of the CcM family of current meters known as secondaries (CcM1c, CcM3-C, CcM1-DC, CcM Hall, CcM Shunt or CcM3-Solar 30.
How do I access the CcM4 energy meter data?
The user can access the data collected through direct communication with the CcM4 via an RS-485 connection, using the Modbus RTU over TCP protocol; or through the herramienta de software ofrecida gratuitamente: el portal web clicMONITOR, que permite la visualización y alojamiento de los datos en la nube a través del CcM WiFi.
El CcM WiFi es un periférico añadido para obtener los datos a través de una red WiFi (véase el manual del dispositivo CcM WiFi, disponible en esta web) y dotar al dispositivo de comunicaciones inalámbricas. La mejor manera de configurar un dispositivo WiFi de la familia de Smart metering CcM es a través de la App clicMONITOR o accediendo a la web interna del dispositivo WiFi mediante su dirección (http://192.168.4.1/).
How to configure the CcM4 Smart Meter?
The combination and use of different devices of the CcM family for submetering offers multiple configuration possibilities, depending on the most convenient in the installation scenario, either for domestic or industrial environments. Thus, it is possible to have a wired, wireless or mixed installation, connecting the different devices together to create communication buses establishing configurable master-slave hierarchies.
In the specific case of the Smart Meter CcM4, the device behaves similarly to a meter or network analyzer. Inserted directly into a three-phase circuit breaker, the device is connected in series with the consumption line, and records voltage, current, power and active and reactive energy values, as well as harmonic distortion of each phase.
