The Generic Object-Oriented Substation Event (GOOSE) protocol is a communication standard used in electrical substations for rapid data exchange. It operates within the IEC 61850 standard and enables real-time messaging between protection and control devices. GOOSE messages use a publish-subscribe model to deliver critical data with low latency and high reliability. This protocol is used…
Traffic Control is a method used to manage network traffic, ensuring optimal performance, prioritization, and efficient data flow. It involves various techniques that control the rate, direction, and volume of traffic within a network. This can include features such as traffic shaping, rate limiting, and Quality of Service (QoS). By controlling traffic, congestion is minimized,…
Ethernet Ring Protection Switching (ERPS) is a network protocol designed to provide fault tolerance and network resiliency in networks. It ensures uninterrupted service by creating a redundant ring topology, where data can be rerouted if a link or device fails. ERPS quickly detects failures and activates an alternative path, minimizing downtime. It enhances network reliability…
Loop Detection is a network feature used to identify and prevent network loops in networks. A network loop occurs when data packets continuously circulate in the network without reaching their destination. This can cause congestion, degraded performance, and even network outages. Loop Detection protocols monitor network topology and detect the presence of loops by analyzing…
MapleLink’s ModbusTCP allows a network device to act as a Modbus TCP slave, enabling remote access by a ModbusTCP master device. With this feature, you can read and write to specific addresses on the device, while other addresses may be read-only. The protocol does not extend ModbusTCP functionality to other connected equipment, focusing only on…
VLAN Data Forwarding is the process of directing network traffic between devices within a Virtual Local Area Network (VLAN). When a packet is sent within a VLAN, it is forwarded based on the VLAN tag. Layer 2 switches use this tag to ensure that the data only reaches devices within the same VLAN, effectively isolating…
Reverse Polarity Protection is a safety feature that prevents damage to electronic devices when the power supply connections are reversed. When the positive and negative wires are mistakenly swapped, reverse polarity can cause equipment to malfunction or even fail. This protection works by ensuring that the device will either not power on or automatically correct…
Power Surge Protection is a safety feature that safeguards electrical devices from voltage spikes or surges. It may occur due to lightning strikes, power outages, or electrical faults. These surges can damage or destroy sensitive equipment by exceeding the device’s voltage rating. Power surge protection works by redirecting or absorbing excess voltage, preventing it from…
Over Voltage Protection (OVP) safeguards devices from voltage spikes and surges that could cause damage. When voltage exceeds safe levels, OVP mechanisms activate to prevent equipment failure. Certifications such as EN 61000-4-5 (Surge), EN 61000-4-2 (ESD), EN 61000-4-3 (RS), EN 55011 (Class A), and UL 61010-1 may indicate potential over-voltage protection features. While these certifications…
ESD Protection refers to the methods and components used to protect electronic devices from electrostatic discharge (ESD). ESD occurs when static electricity is suddenly released, which can damage sensitive electronic components. This type of protection ensures that devices, such as network equipment or computers, are shielded from these discharges, preventing potential malfunctions or failures. This…
Code redundancy refers to the practice of adding duplicate or backup code within a system to enhance its reliability and fault tolerance. By including extra functions or processes, systems can continue to operate smoothly even if one part fails. This technique is commonly used in error detection and error correction methods to ensure uninterrupted service.…
Maple Systems products offer the ability to remotely reboot a device. Maple Network Switches can be remotely accessed via its HTTP/HTTPs or TELNET/SSH servers. Once connected you may reboot the system. Maple System cMT / cMT X Series HMIs have a similar functionality. Allowing for users to reboot the system remotely through its system settings…
