8. Frequently Asked Questions (FAQ)

Q1: Which marine automation systems is this RHUB200-5 compatible with? Can my ship use it?

A: The RHUB200-5 is mainly compatible with Kongsberg K-Chief series marine automation systems (such as K-Chief 500, K-Chief 600, K-Chief 700, etc.), serving as a hub and repeater for RBUS remote I/O process bus. Whether your ship can use it requires confirmation:

Whether the ship automation system is Kongsberg K-Chief series (or compatible K-Chief system)
Whether the system uses RBUS to connect remote I/O modules
Model of existing hubs/repeaters in the system (whether RHUB200-5 or compatible model)
Number of RBUS ports to expand and communication distance
Ship classification society requirements (product needs to pass corresponding classification society certification) It is recommended that you provide the ship automation system model, network topology diagram, existing hub model, and we can assist in confirming compatibility. If your system is not K-Chief series, we can also recommend network equipment for the corresponding system.

Q2: How many ports does RHUB200-5 have? What does the "5" mean? How many I/O modules can it connect?

A: The RHUB200-5 is equipped with 5 RBUS bus ports, the "5" in the model indicates 5-port configuration.

Regarding the number of connectable I/O modules:

Each RBUS port can connect one RBUS bus segment, each bus segment can 串联 multiple remote I/O modules (such as RMP420, RDIOR420, RDIO401S, etc.)
The specific number of modules connectable per bus segment depends on bus length, communication rate, signal quality and other factors, usually one bus segment can connect several to more than ten modules
5 ports can theoretically connect 5 bus segments, total can connect dozens of remote I/O modules, meeting needs of most marine automation systems
Actual connectable quantity needs to be determined according to system network planning and field conditions, recommended to refer to Kongsberg system design guide

Port assignment recommendation:

1 port for uplink connection to RCU main controller (or upper-level hub)
Remaining 4 ports for downlink connection to remote I/O modules or bus segments in different areas
Can also be flexibly assigned according to actual topology, such as when building redundant ring network, two ports respectively connect two directions of the ring

Note: The RHUB200-5 is an RBUS bus hub, not an Ethernet switch, cannot directly connect Ethernet devices. If Ethernet switch is needed, there are dedicated network switch devices in Kongsberg systems (such as HP 3600-24, etc.).

Q3: What is the difference between RHUB200-5 and ordinary Ethernet switches? Can ordinary switches be used instead?

A: RHUB200-5 and ordinary Ethernet switches are completely different devices, cannot be substituted for each other:

表格

Comparison Item	RHUB200-5	Ordinary Ethernet Switch
Bus Type	RBUS (RS485-based serial bus)	Ethernet
Physical Layer	RS485 differential signal, shielded twisted pair	RJ45 or fiber, Ethernet physical layer
Protocol	Kongsberg proprietary RBUS protocol	TCP/IP, Ethernet protocol
Purpose	Connect remote I/O modules (RMP420, RDIOR420, etc.)	Connect computers, servers, IP devices
Real-time	Industrial real-time bus, deterministic communication	Non-deterministic, suitable for general data communication
Environmental Adaptability	Marine-grade, wide temperature, high EMC, classification society certified	Commercial or industrial-grade, usually no classification society certification
Power Supply	Dual redundant 24VDC	Usually single power supply, 110/220VAC or 24VDC

Why ordinary switches cannot be used instead:

Physical layer incompatibility: RBUS is RS485 serial bus, Ethernet is RJ45 differential signal, physical interface and level are completely different, cannot directly connect
Protocol incompatibility: RBUS uses Kongsberg proprietary protocol, Ethernet uses TCP/IP protocol, protocol stacks are completely different, cannot interoperate
Real-time requirements: Remote I/O communication in marine automation systems requires determinism and real-time, ordinary Ethernet switches cannot guarantee
Certification requirements: Marine equipment requires classification society certification, ordinary switches usually do not have
Environmental adaptability: Ship engine room environments have high temperature, high humidity, strong vibration, strong electromagnetic interference, ordinary switches cannot adapt

Conclusion: Must use Kongsberg original RHUB200-5 or compatible RBUS hub, cannot use ordinary Ethernet switch instead. If there is Ethernet communication requirement in the system (such as operator station, server connection), should use Kongsberg-certified industrial Ethernet switch.

Q4: How to connect dual redundant power supplies? Can it work with only one power supply connected?

A: The RHUB200-5 is equipped with dual redundant 24V DC power inputs, designed to improve system reliability.

Dual power wiring method:

The module has two independent 24V DC power input terminals (usually marked as Power 1 and Power 2, or main power and backup power)
It is recommended to use two independent 24V DC power supplies, for example:
- Power 1: 24V DC power from ship main power (main switchboard)
- Power 2: 24V DC power from ship emergency power (emergency switchboard) or UPS
Positive poles of two power supplies respectively connected to positive poles of two power input terminals, negative poles respectively connected to negative poles (common negative)
Pay attention to power polarity, avoid reverse connection (module has reverse polarity protection, but should still be wired correctly)
Voltages of two power supplies should be consistent, both within 18-32V DC range

Can it work with only one power supply connected?

Yes, it can work. The RHUB200-5 supports single power operation, when only one 24V DC power supply is connected, the module can work normally
But at this time, power redundancy function is lost, if this power supply fails or is de-energized, the module will stop working, affecting automation system operation
Strongly recommended to use dual redundant power supplies, especially in critical ship systems, dual power redundancy is an important measure to improve system availability
If temporarily only one power supply is connected, should complete the second power supply as soon as possible to restore redundant configuration
During single power operation, power indicator may have corresponding status indication (such as backup power fault alarm), specific refer to module manual

Power redundancy test:

During normal system operation, can periodically test power redundancy function: under premise of ensuring safety, disconnect one power supply, confirm module continues to operate, communication is not interrupted, then restore power, confirm both power supplies are normal
During testing, should notify duty personnel to avoid system alarms caused by testing

Q5: Is this product in stock? What is the lead time? What is the price?

A: This model is currently in order available status, standard lead time 4-8 weeks (ordered from Kongsberg Maritime factory or allocated from global inventory). The RHUB200-5 is a dedicated marine automation network device, with limited stock inventory, usually requiring production to order or allocation from global inventory.

Q6: How to judge and replace a faulty RHUB200-5? Does it need reconfiguration?

A: Fault judgment methods:

Indicator Status: Observe status indicators on RHUB200-5 front panel:
- Power light: off → power fault or module damaged
- Bus link light: a certain port off → that port bus connection fault or not connected
- Communication fault light: on or flashing → bus communication abnormal
- Module error light: on → module hardware fault
System Alarm: K-Chief operator workstation will display network communication fault, remote I/O module communication interruption and other alarm information, can locate to specific RHUB200-5 and port
I/O Data Abnormality: All remote I/O module data connected under a certain RHUB200-5 simultaneously abnormal or lost, may be hub fault or that bus segment fault
Multimeter Measurement: Measure whether 24V power input is normal, whether RBUS bus signal is normal, determine whether it is power problem, bus problem, or module itself fault

Replacement steps:

Notify duty personnel and captain (if 涉及 safety system), explain that module replacement will be performed
If this hub connects critical equipment, first confirm system status, take temporary measures if necessary
Disconnect RHUB200-5 dual 24V DC power supplies
Wait for module to fully discharge
Mark port positions of all RBUS bus connections (or take photos for record)
Disconnect all RBUS bus connectors and power wiring
Press DIN rail clip, take out faulty module
Install new module on DIN rail, ensure clip is secure
Restore all RBUS bus connections and power wiring per marks
Turn on dual 24V DC power supplies
Observe module indicators, confirm power, bus link, communication fault, module error and other indicator status normal
In K-Chief system, confirm all connected remote I/O modules resume communication, data normal
Test communication function of each port
Record replacement date, module serial number, fault symptoms and other information

Regarding reconfiguration:

Usually no reconfiguration required. The RHUB200-5 is a transparent bus hub and repeater, does not need to store configuration parameters, plug-and-play. After replacing new module, as long as wiring is correct, module automatically works after power-on, no need to download configuration or programming.
But need to confirm:
1. New module model and version consistent with original module (RHUB200-5)
2. All bus connections restored per original positions, port assignment correct
3. Termination resistor positions correct (both ends of bus)
If communication is abnormal after replacement, should check:
1. Whether power supply is normal (both channels connected)
2. Whether RBUS bus A/B polarity is correct
3. Whether termination resistors are installed correctly
4. Whether bus cable is damaged
5. Whether connected remote I/O modules are normal
Recommended to perform comprehensive communication test after replacement, confirm all I/O modules and signals normal
