Parallel Redundancy
Protocol (PRP) Switch

Features:

• Ruggedized construction. IEC 61850-3 Compliant. Suitable for industrial applications.
• Available in compact DIN Rail and 19-inch Rack Mount with 1+1 power supply options.
• Total number of Ethernet Ports: 3
• One Interlink Port: Input Ethernet Port (Optical / Electrical - User Selectable).
• PRP/HSR #1: Protected Ethernet Port (Optical / Electrical - User Selectable).
• PRP/HSR #2: Protected Ethernet Port (Optical / Electrical - User Selectable).
• Compliant with IEC 62439-3 specifications.
• Zero recovery time and zero packet loss in case of the failure of either of the (parallel) transmission links. A single network fault will not result in any frame loss.
• Support IEEE-1588v2 Precision Time Protocol (PTP) transparent clock functionality.
• Network loop detection and removal.
• Cut-through and store-and-forward operation.
• Quality of Services (QoS) with priority tagging packet filtering and four priority queues per port.
• Port-based VLAN, VLAN tagging - Max number VLANs is 4094.
• Per port packet filtering.
• Support for MAC address-based authentication methods.
• Operating Modes: PRP, HSR and PRP+HSR.
• Maintenance: The network is fully operational even during maintenance as any intermediate network device (such as an Ethernet Switch) can be disconnected and replaced without breaking the network connectivity.
• Applications include critical network applications, smart-grid, electrical substation automation, industrial automation, critical automotive and military communication applications.

Failsafe* : In Electrical Ethernet Mode.

In-built Electrical and Optical Ethernet Interface Options. Provides both optical and electrical ethernet interface options on the “Protected side” as well as the “PRP sides”.

Ultra-Resilient and Failsafe* – Never itself becomes a point of failure in the electrical ethernet mode. The “protected interface” automatically reverts to and reconnects to the “primary PRP interface” even in a power down condition. It is the only such PRP solution available in the industry which ensures that the VCL-2724 PRP Switch, itself, never becomes a point of failure!!!
