Rolls-Royce H1111.0203 | H6036 1.0 GHz Marine Controller

Description

Rolls-Royce Marine H1111.0203

Product Introduction

A failed marine controller creates a different procurement problem from a normal PLC replacement: the hardware may be physically interchangeable while the installed software and vessel configuration are not. The Rolls-Royce Marine H1111.0203 is identified as a marine automation main controller, associated with RR Part 75670 and the H6036 / 1.0 GHz hardware platform. Records also identify BIOS K6036001.008 and PIC Code Rev. 2.2, making those identifiers useful when screening legacy spares.

In a vessel automation architecture, this type of controller serves as a central computing and control element rather than a conventional standalone PLC I/O card. It may participate in propulsion, machinery, power-management, or other vessel-control functions depending on the original project configuration. Public sources make broader claims about CAN, Profibus, Ethernet, and other interfaces, but they do not establish that every H1111.0203 has the same physical interface population. For a replacement, the installed unit and vessel documentation should take precedence.

Key Technical Specifications

The 75670 / H6036 / 1.0 GHz / K6036001.008 / PIC Rev. 2.2 combination is the strongest identification set found across current records.

I would not publish a fixed supply voltage, I/O channel count, exact Ethernet/Profibus port configuration, operating-temperature range, or protection rating for this exact part number without the original Rolls-Royce system documentation. Current secondary listings provide inconsistent values, so using those figures as design specifications would create unnecessary replacement risk.

Application Scenarios & Field Considerations

Vessel Automation Main Controller

The H1111.0203 is relevant where a vessel retains a Rolls-Royce marine automation architecture and requires an exact or closely controlled controller spare. Its role is at the processing/control level rather than being simply an analog or digital I/O expansion card.

Propulsion and Machinery Control

Marine records associate the H1111.0203 with propulsion, machinery, power, and vessel-control applications. The actual control responsibilities depend on the vessel project, application software, and connected subsystem architecture.

Legacy Marine System Maintenance

For older vessels, the controller’s hardware identifiers are particularly important. A spare marked only “.0203” should be inspected for 75670, H6036, BIOS K6036001.008, and PIC Rev. 2.2 before being accepted as a replacement.

Vessel Automation Migration

During a marine automation migration, an existing .0203 may need to remain operational while the replacement architecture is engineered and tested. In that situation, preserve the existing application image, network settings, node identity, configuration data, and interface assignments before removing the controller.

Related Products

• H1127.0101 — Rolls-Royce Marine H6045 / 433 MHz controller; different hardware designation, so it should not be treated as a direct replacement.
• H6036 — hardware platform associated with .0203.
• Rolls-Royce CCN 01 CANMAN Controller — related marine control/network equipment; system compatibility must be checked.
• RRAIO16 — Rolls-Royce Marine I/O module family; serves a different role from the .0203 main controller.
• H6045 — controller platform associated with the H1127.0101 family, useful for distinguishing controller generations/configurations.

These are system-level references rather than confirmed drop-in substitutes. A marine controller should never be selected solely because another part belongs to the same manufacturer’s automation family.

Engineer’s Guide — Field Pitfalls to Avoid

1. Match the Hardware Identity, Not Just the Model Number

For this unit, 75670 + H6036 + 1.0 GHz + BIOS K6036001.008 + PIC Rev. 2.2 provides a much stronger identification trail than the .0203 designation by itself.

2. Firmware Is Part of the Replacement

A controller can power up and pass a basic hardware test while still being unsuitable for the vessel. Verify firmware, PIC revision, application software, node identity, and configuration against the controller being replaced.

3. Do Not Assume Every Communication Interface Is Populated

Secondary records cite CAN, Profibus, Ethernet, and other interfaces, but there is insufficient public evidence to establish one universal interface configuration for every .0203. Inspect the actual connector arrangement and compare it with the vessel drawings before installation.

4. Check Revision 2.2 Carefully

Several current inventory records specifically identify Rev. 2.2 / PIC Code Rev. 2.2. A controller with the same basic part number but a different revision should be treated as a configuration question, not automatically accepted as equivalent.

5. Be Careful With Used or “For Parts” Inventory

Current market records include units explicitly listed as for parts / not working, as well as used units. Therefore, the part number alone says nothing about whether a particular physical unit has passed a functional test.

6. Do Not Substitute by CPU Speed Alone

The / 1.0 GHz designation is useful for identification, but processor frequency does not establish application compatibility. Software image, BIOS, PIC, interfaces, configuration, and vessel-specific engineering all matter.

FAQ

What is the Rolls-Royce .0203?

It is a Rolls-Royce Marine automation main controller, identified with RR Part 75670 and the / 1.0 GHz hardware platform. Current records also associate it with BIOS K6036001.008 and PIC Code Rev. 2.2.

What is the difference between .0203 and H1127.0101?

They are different controller assemblies. .0203 is associated with , while H1127.0101 is associated with H6045 / 433 MHz. Similar marine-control applications do not make them automatic substitutes.

Is .0203 a PLC CPU?

Functionally, it is closer to a marine automation main/system controller than a conventional modular PLC CPU. Its exact system role depends on the Rolls-Royce vessel architecture and application software.

What BIOS is associated with .0203?

The matching records identify . This should be checked against the installed controller during replacement work.

What PIC revision is associated with this part?

The commonly documented configuration is PIC Code Rev. 2.2. A different PIC revision should be investigated before it is accepted as an equivalent spare.

Does .0203 support Ethernet, CAN, and Profibus?

Those interfaces are reported by secondary sources, but the public evidence does not establish that every .0203 has the same physical interface configuration. For engineering purposes, verify the actual controller connectors and the vessel’s approved documentation rather than relying on a generic listing.

What should be checked before purchasing a replacement?

Confirm , RR Part 75670, , , PIC Rev. 2.2, physical connector configuration, firmware/application data, and actual condition. For a vessel-critical controller, functional test evidence is also preferable to a simple visual inspection.
