L'édito de Vincent BedouinSOFREL S4W
4.0 telemetry RTU for connected and cybersecured water networks
Resulting from five years of development, the SOFREL S4W is designed to meet the latest needs of water network operators. This is not only a compact, connected and sturdy industrial product, but a complete telemetry network management solution.
Its simplicity of implementation and use via graphics-based, user-friendly software make the daily life of users as easy as possible. The continuity offered by SOFREL solutions will allow this new remote terminal unit to be deployed seamlessly within existing SOFREL telemetry networks.
The SOFREL S4W and its ecosystem bring telemetry into a new era: telemetry 4.0
Compact devices, industrial design
These compact and sturdy S4W devices all have the same hardware architecture. They include a 2G/3G/4G modem and an Ethernet port. Further communication modules (radio, RS485, RS232, etc.) and I/O extension modules can be added to the front panel to increase the number of inputs/outputs.
Their key distinction concerns the number of I/Os contained within the case:
- SOFREL S4W Small: 8DI, 2AI, 2DO
- SOFREL S4W Medium: 12DI, 2AI, 4DO + possibility of 2 I/O expansion modules
- SOFREL S4W Large: 16DI, 4AI, 4DO + possibility of 10 I/O expansion modules
- SOFREL S4W Dual: 8DI

Simplified installation and set-up
The S4W’s ergonomics can be appreciated as soon as it is installed in an electrical enclosure, with a reduced size and easier wiring thanks to intuitive marking and removable spring-loaded terminal strips. DIN-rail mounting with automatic grounding also makes the S4W easier to install. Remote power feeding of the 4-20mA-current sensors takes place directly via the S4W’s Analog Inputs (AIs). The I/Os are entirely software configurable (no switches to be positioned on the boards).
The S4W-Tools utility enables extremely simple and user-friendly configuration. A highly impressive graphical environment represents the product and all its modules. The numerous software wizards (parameter self-monitoring, dynamic error band, etc.) guide the user step-by-step. Configurations can be imported or exported via an Excel-compatible file.The S4W-Tools utility enables extremely simple and user-friendly configuration.

Operating convenience
In order to facilitate the exploitation of the data managed by the S4W locally or remotely, the operators have two graphical consultation interfaces.
S4-Display is a colour touch-sensitive display that can be integrated into the front panel of the control cabinet. It allows the visualisation of mimic diagrams, data and curves on site. There is nothing to set up on S4-Display. Completely “plug and play”, the controlled data is displayed as soon as S4-Display is installed in the cabinet.
S4-View is a Windows based software for viewing the data managed by S4W. It also allows remote diagnosis of its equipment (hardware tests, logs and operation monitoring).
Graphics-based configuration of the lift station
Configuration is very simple to perform via a view representing the lift station. Pumping automation (2 or 3 pumps) is fully managed by the S4W (pumping control, pump sequencing, grease-ring and deposit prevention offset). The S4W monitors pumping efficiency by recording the running times and average flow rates of each pump. Based on these calculations, it detects clogged or worn pumps and informs the operator of any overflow.
An onboard HTML5 web server
The Plug & Play web server (HTML5 and responsive) enables users to securely access their S4W data from any terminal (smartphone, tablet or PC).
They can monitor and acknowledge alarms and adjust setpoints remotely using the web browser.
Animated mimic diagrams can be defined in each S4W, with the ability to navigate between mimic diagrams. The web server provides access to dynamic, zoomable information curves to facilitate data and event visualization.
Secure communication
As an integral part of LACROIX Sofrel’s DNA, efficient, secure communications are the S4W’s key strengths.
Equipped with a multi-operator SIM card, the device offers tests to choose the best operator (reception level, network latency, successful transmission %, etc.)
In the event of ADSL outage, the S4W automatically transfers communications to the 4G interface to ensure data transmission continuity.
Process control for adapting to specific use cases
In addition to its dedicated water functions, the S4W also includes a highly comprehensive process-control suite. This module uses standard programming languages (ST, Ladder, Function Blocks, Grafcet) and provides an extensive library of system and sector-specific functions, alongside a wide selection of development tools.
