Hirschmann EAGLE40 Industrial firewalls; Next-gen cybersecurity solutions
H E
irschmann’s EAGLE40 series firewalls are designed to deliver cutting-edge industrial cybersecurity, tailored to meet the complex demands of sectors like oil and gas, and power transmission. These next-generation devices assist in adhering to key regulations such as NERC CIP, IEC 62443, and NIST, ensuring robust compliance and industry approvals. The EAGLE40 firewalls feature a multi- layer design to combat sophisticated cyber threats, with the EAGLE40-07 offering
advanced intrusion detection and protection. Optimized for deep packet inspection (DPI), they handle diverse industrial protocols effectively, combined with stateful packet inspection (SPI) for enhanced security. User-friendly and versatile, the EAGLE40 series supports IT/OT convergence, offering a comprehensive multi-deployment solution without compromising network uptime. The intuitive graphical interface and firewall learning mode make configuration accessible for OT teams of varying skill levels.
Performance-wise, EAGLE40-03 provides 3x GbE ports with up to 1 Gbps throughput, while EAGLE40-07 features 7x GbE ports with up to 5 Gbps throughput. These firewalls are built to withstand harsh industrial conditions, operating reliably from -40°C to +70°C within ruggedized, convection-cooled metal housings.
Integration with Industrial HiVision solutions enhances management and monitoring, making the EAGLE40 series a comprehensive and robust choice for
maintaining cybersecurity and maximizing uptime in critical industrial environments.

lectrical heating systems have several safety features built in to prevent dangerous situations. High- limit sensors, or safety sensors, are one of the most important. Not only do they protect people, they help keep manufacturing lines running by limiting damage to equipment and product. In this article, Jeremy Ohse at industrial heater, temperature sensor, and controller manufacturer Watlow, explores best practice and considerations for high-limit safety sensors:

Thermal loops consist of a heater, temperature sensor, and heater controller. The controller has a temperature setpoint,
In an application away from industry, a
receives a signal from the temperature sensor, and modulates power to the heater to maintain the temperature setpoint. If there is a failure in the primary thermal control loop, the
redundant safety sensor can tell the controller to reduce power to the heater or shut down the entire system. The most common failures are physically damaged sensors, worn out components, and pinched wires.
hot tub uses a high-limit sensor to prevent the water from getting too hot. If the primary control loop fails, the heater will continue to heat the water. When the water temperature reaches a certain level, usually between 110 and 120 °F, the high-limit sensor disables the heater to keep the water at a safe, enjoyable temperature.
To provide additional safety, when the high-limit sensor trips the system, users are “latched out” until the system is inspected
and reset by an operator, system designer, or manufacturing engineer. Once the system is repaired and reset, it will operate normally again. In the hot tub example, the high-limit sensor will likely disable the pump in addition to the heater. A technician may need to inspect the hot tub and replace the primary sensor — or other defective parts — before resetting the system. This safety latch is often achieved in industrial systems through a programmable temperature controller and mechanical relay… Read the full article at:
