VCL Products > Industrial Grade Switch > VCL-2724, Parallel Redundancy Protocol (PRP) Switch
The unit is Failsafe, and it never becomes a point of failure in the electrical Ethernet mode. The “protected interface” automatically reverts to and reconnects to the “primary interface” even in a power-down condition.
VCL-2724, Parallel Redundancy Protocol (PRP) Switch
The VCL-2724 PRP/HSR Switch is a simple, compact, easy-to-use solution designed to be used in critical Ethernet networks that cannot afford packet loss, which may otherwise occur during ring recovery or switchover upon failure of either one of the Ethernet LANs. The VCL-2724 is designed to carry critical Ethernet data over two parallel LANs with zero packet loss.
The VCL-2724 PRP/HSR Switch may also be used to carry Ethernet data over an HSR ring with absolutely no packet loss. VCL-2724 PRP/HSR Switch is the only presently available in the industry that ensures that the PRP/HSR Switch never itself becomes a point of failure, even in power-down condition.
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 of 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 grids, electrical substation automation, industrial automation, and 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 does it become 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 that ensures that the VCL-2724 PRP Switch itself never becomes a point of failure!!!
