Skalar.pro - Reliable Data Communication - at Low Cost!

Skalar.pro enables IP-based data transmission via DSL/Ethernet or mobile radio network, thereby ensuring excellent communication with different locations and enabling the use of nearly all available mobile radio standards - from 2.5G to 4G, which guarantees maximum bandwidth.

In accordance with the Radio Equipment Directive (RED), effective as of August 1, 2025, communication devices such as Skalar.pro may only be placed on the market if they comply with the requirements of EN 18031. This regulation imposes enhanced requirements on IT security and data protection and is mandatory for all manufacturers.

With the Skalar.pro devices, VIVAVIS offers a future-proof solution that meets all requirements of the Radio Equipment Directive (RED) applicable as of August 1, 2025. From firmware version V01.27 onwards, the device fully complies with the IT security requirements in accordance with EN 18031-1 and EN 18031-2. Continuous firmware development also ensures the highest levels of security and reliability for your Skalar.pro use case going forward.

Reliable protection against external influences is more important than ever in modern metering communication. The proven VPN functionality in Skalar.pro enables secure, encrypted data transmission while simultaneously ensuring transparent communication by allowing direct meter communication to pass through using data transmission protocols such as IEC 62056-21 (formerly IEC 1107), M-Bus, and others. This ensures continued seamless operation with existing remote meter reading systems. As a result, no new protocols need to be introduced to meet the required standards for confidentiality, integrity, and authenticity.

Naturally, Skalar.pro relies on modern, recognized cryptographic methods in accordance with the technical guideline BSI TR-02102. By choosing Skalar.pro, you are investing not only in compliance but also in a robust, field-proven solution that delivers security and flexibility in line with regulatory requirements for the future.

Meters can be connected either via integrated serial interfaces acc. to CL1, RS232, RS485 or M-Bus Master (optional; wired or wireless). An adjustable and activatable direct-voltage output is available for the supply of external interfaces.

Various software expansions, such as pro.online and pro.monitor, provide a comprehensive overview of all available data. For this purpose, pro.online converts raw data into other formats (e.g. CSV); pro.monitor, on the other hand, converts output values and sends a message to the person in charge in the event of an upward or downward setpoint violation.

Customers can choose between conventional three-point housings for installation with a variety of meters, or a top-hat rail housing (modular system). Skalar.pro II DR (DIN Rail) includes the most important functions of Skalar.pro, as well as various expansion options.

The PRM44 module replicates meter readings by means of energy-proportional pulses and can thus record and process energy consumptions.

The PRM44 module has four configurable PhotoMOS outputs for switching of DC/AC. This module is an expansion for the three-point housing of Skalar.pro.

In connection with the IDSpecto.ADMIN software, Skalar.pro constitutes a complete solution for remote meter reading.
