The high level of customer confidence speaks for itself. We enable the reliable transport of energy and data.

Use cases from the energy industry

Communication technology connection
of a transformer stationintelligent local network stations

Measurement data is transferred to the cloud by setting up advanced network architectures based on IPv6, Dual APN, OSPF and RIP. The zero-trust principle is used to ensure a supply chain free of sensitive secrets, both in startup and running configuration mode. An automatic certificate exchange (EST) and the separation of the control channel and data channel contribute to security. The cryptographic procedures comply with BSI TR-02102 standards and high availability is ensured by connection redundancy over various channels such as DSL, fibre and LTE, including LTE450 MHz communication for critical infrastructure.

Communication connection of a gas pressure regulator station

Measurement data is transmitted to control and cloud systems using secure communication via public or private networks, utilising both OpenVPN and IPsec. Fault messages and alarms are transmitted effectively via SMS, email and MQTT. The icom Connectivity Suite also enables remote maintenance and remote access to network devices. The flexible connection technology includes LTE, LTE450, fibre optics and DSL. To ensure high availability, this technology relies on redundancy, both in the area of fibre optics and LTE as well as between different LTE connections (LTE1 & LTE2).

Communication technology for energy and gas grids – Frequently asked questions

What is the difference between an industrial router and a home router?

Service life, availability, IT security
Home routers are developed for a service life of 2-3 years and the electrical components are selected accordingly. In harsher environmental conditions, e.g. temperature fluctuations in control cabinets or increased EMC/vibration, this service life is significantly reduced. Industrial routers have a service life of 10+ years. The use in industry and infrastructure does not allow frequent changes.

Industrial applications rely on high communication availability. The router system has been developed for uninterrupted 24/7 operation.

Security – Interesting facts about the IT security of industrial routers
Infrastructure and industrial plants are attractive targets for cyber criminals. The router operating system is specially developed and hardened for these applications and offers functions for secure operation in critical infrastructure.

Is INSYS certified for critical infrastructure?

INSYS has received a security certificate for critical infrastructure from the German Federal Office for Information Security for the MRX3-LTE. Further information on the IT security. For all products, regular Penetration tests carried out by an independent body.

Is it possible to operate several VPN tunnels in parallel?

Both OpenVPN and IPsec tunnels to different remote stations can exist in parallel. The networks are completely isolated from each other and can therefore also be used for external participants.

Can I access surveillance cameras remotely?

With a router installed on site and the web proxy function of the icom Connectivity Suite, surveillance cameras can be accessed directly in the browser. This does not require a VPN client on the end device.

How and where are industrial routers installed?

Industrial routers are clicked onto a top-hat rail (DIN rail) in the electrical enclosure or screwed directly to the housing or a bracket.
With mobile routers, the external mobile phone antenna is routed out of the control cabinet and mounted on the outside wall of the building.

Which SIM cards are suitable for the water industry?

Most faults in mobile routers can be traced back to SIM cards. For this reason, we offer licensed multi-roaming industrial SIM cards at favourable conditions. We have the most experience and test coverage with these SIM cards. AAll the advantages at a glance.
