ON OUR RADAR 57
A COMPLETE PROCESS CONTROL
SUITE AND A VAST LIBRARY OF
“WATER USE CASES” FUNCTION
BLOCKS
The installation processes are published in
a process control suite included in SOFREL
YDRIX. The powerful suite is compatible
with the IEC 61131-3 standard and offers
standard programming languages: ST,
Ladder, FBD and SFC (Grafcet). Integrators
also have a vast library of function blocks
dedicated to the water business (volume
calculations, flow rates, PID regulation
function, etc.). For wastewater lift stations,
in particular, the software has all the
functions required to control the pumps
and manage pump efficiency. Process
control technicians can use a wide range of
test, simulation and online debug tools to
develop and adapt their programs on site or
remotely.
COMPLIANT WITH DNP3 AND
IEC-60870-5-104 PROTOCOLS TO
INTERFACE WITH ALL SCADA
Interoperability with the TCP/IP networks
and operators’ supervisors is guaranteed
by the standard communication protocols
DNP3 and IEC-60870-5-104 supported
by SOFREL YDRIX. Based on these
protocols, the RTU fits perfectly into the
existing telemetry and SCADA networks
and communicates securely with any
standardised industrial SCADA software.
SECURE COMMUNICATIONS AND
CYBERSECURITY INTEGRATED
SOFREL YDRIX supports VPN server
protocols that ensure the cybersecurity of
the infrastructure. The RTUs and operational
supervisors are authenticated and certified. The
data exchanged between its connected systems
is fully encrypted. To complete all this, SOFREL
YDRIX can interface with a Syslog server that
tracks events in an operating log.
The YDRIX RTUs are “full IP”; they communicate
via their 2G/3G/4G modems or their ethernet
links to the SCADA Central Station. These
multiple systems allow for redundancy between
the communication media. In the event of
a failure on the main telecommunications
network, SOFREL YDRIX automatically switches
to secondary support and returns to normal
when the initial network operates again.
Operators can rely on this system to never lose
information and to recover all their network
data in real time.
M2M COMMUNICATION WITH
SOFREL LS/LT DATA LOGGERS
The SOFREL LS and LT data loggers located
on sites isolated from the network (reservoirs,
manholes for metering or pressure monitoring,
etc.) can communicate with a remote SOFREL
YDRIX. Either periodically or when a certain
level has been exceeded, SOFREL YDRIX
receives the information from the data loggers
and decides whether to fill the reservoir while
also taking into account the needs of the
network and electricity price periods. They also
allow remote control of pressure on the water
distribution network.
By combining expertise in the telemetry &
telecontrol over IP or 4G connection, water
sector and cybersecurity SOFREL YDRIX
provides an extremely innovative solution
to guarantee the safety and performance of
drinking water and wastewater networks.
