DCS Network Routing and Signal Compensation
- Integrates dual-redundant V-net 10BASE-2 coaxial physical layer routing with high-speed Vnet/IP Ethernet bridges to maintain deterministic data packet delivery across distributed control segments.
- Implements channel-to-channel isolation between field network segments to prevent common-mode electrical noise and earth potential differences from degrading bus signal integrity.
- Executes hardware-level switchover between dual communications paths without packet loss, preserving real-time control variable synchronization across CENTUM architecture domains.
Frequently Asked Questions
Q: What physical media connectors are utilized for network bridging on the AVR10D-Q22020?
A: The router utilizes BNC connectors for the 10 Mbps V-net coaxial interface and standard RJ45 connectors for the 100 Mbps full-duplex Vnet/IP interface.
Q: How does the power supply configuration function in high-availability installations?
A: The Q22020 specification incorporates dual AC power supply circuits accepting 220-240 V AC input, enabling continuous router operation during a failure of one line feed.
Q: What is the primary functional isolation rating between the network channels?
A: The hardware incorporates channel-to-channel electrical isolation to suppress loop currents and shield internal logic components from transient ground surges.
Field Installation Guidelines
- Mount the router chassis onto a flat vertical surface or within a standard control enclosure, maintaining a minimum 50 mm clearance around ventilation slots for convective cooling.
- Terminate V-net coaxial connections using 50-ohm BNC connectors and verified bus terminators at the physical ends of the cable segment to prevent signal reflections.
- Connect the frame ground (FG) terminal directly to a dedicated low-impedance industrial earth ground bar using a short, heavy-gauge conductor.
- Verify dual AC feed voltage levels with a calibrated multimeter before energizing the individual power terminal blocks on the router assembly.
