Micrologic X Control Unit in Enerlin'X Digital Systems


  • Bluetooth Smart technology with wireless encrypted (AES-128) communication (IEEE 802.15.1).

  • Proprietary connectivity with wireless encrypted (AES-128) internal communication (IEEE 802.15.4).

  • NFC operates in very short range (a few centimeters).

  • Pairing method and encryption is compliant with NIST 800-121.


  • Only Schneider Electric-signed firmware can be installed on the Micrologic X control unit.

  • Only Schneider Electric-signed digital modules can be installed on the Micrologic X control unit.

  • Only Schneider Electric-signed ULP modules can be installed on an IMU.


  • Access control done by password. To be initialized by the user to change the default values.

  • Restricted USB usage for communication profile only (no mass storage).

Micrologic X control units can be incorporated in Enerlin'X digital system using EIFE and IFE interface modules. Enerlin’X provides a simple and reliable link to local LCD displays and expert applications over Ethernet.

It makes available on Ethernet most of the information collected in the circuit breakers and other electrical devices installed in a low voltage electrical equipment: Status, measurements, counters and alarms etc.

System Security

Operational security is important for electrical installations when it comes to local and remote interaction. Confidentiality, integrity and availability (also known as the AIC triangle) is a model designed to guide policies for information security within an organization and these elements are considered as the three crucial components of security.

In this context, confidentiality is provided by rules that limit access to information (equivalent to privacy), integrity means the information is trustworthy and accurate, and availability means there is reliable access to the information by authorized people.

Bluetooth Smart Connectivity

Micrologic X control units are equipped with Bluetooth 4.0 Smart wireless communication which allows a connection with a smartphone equipped with the same technology. Bluetooth Smart complies with the IEEE 802.15.1 standard.

NFC Connectivity

Micrologic X control units are equipped with near field communication (NFC), which allows data exchange with a smartphone equipped with the same technology and follow the standard ISO/IEC 15693-3.

Proprietary Connectivity

Micrologic X control unit are equipped with a proprietary connectivity means based on IEEE 802.15.4 standard which allows a connection with a Com'X module.

ULP Connectivity

ULP is a fast communication link dedicated to circuit breaker monitoring and control. It connects the circuit breaker to an Ethernet interface or an IO module. ULP operates at a speed of 1 Mb/s and is plug & play.

Ethernet Connectivity

Ethernet is a data link and physical layer protocol complying with the IEEE 802.3 standard. It operates at a speed of 10, 100 or 1000 Mbps. The maximum length of Ethernet cable between two devices is 100 m (328 ft.).

IFE and EIFE Ethernet interfaces can be connected to a PC, a laptop or a PLC over Ethernet.

The IFE Ethernet switchboard server provides a Modbus TCP/IP gateway over Ethernet to enable Modbus TCP communication from a Modbus TCP master to any Modbus slave devices connected to it. The maximum active Modbus TCP client connection is twelve.

IFE and EIFE Ethernet interfaces have an embedded web server (web page).

Modbus Connectivity

Modbus SL (RTU) is a communication protocol widely used in industrial networks. It operates according to a “master-slave” mode, where the slaves communicate one at a time with the master. This is an RS 485 open bus on which communicating Modbus devices are connected. All types of PLCs and microcomputers may be connected on to the bus.

The maximum number of devices that may be connected to a bus depends on the type of devices, the baud rate (19200 is recommended), the volume of data exchanged, and the expected response time. The RS 485 physical layer offers up to 32 connection points on the bus (1 master, 31 slaves).

Maximum recommended length for Modbus SL (RTU) bus is 1200 m (3940 ft.).
