Berghof C1CPU-4S-07 M3000 PLC CPU Module

Key Technical Specifications

Berghof documentation confirms the exact C1CPU-4S-07 / 2010027 identification. A current industrial supplier also identifies the unit as a Berghof PLC unit and specifies 24 V DC.

Some secondary sources publish detailed processor, memory, I/O, communication, and environmental specifications for C1CPU-4S-07, but these specifications conflict across listings. For example, one source describes an M3000 CPU module, while another gives specifications that appear to belong to a different compact controller configuration. Those values should therefore not be treated as OEM-confirmed specifications for this exact suffix.

Product Introduction

The Berghof C1CPU-4S-07 is a PLC CPU/controller module used in Berghof industrial automation systems. Berghof documentation assigns this exact model the OEM part number 2010027. The closely related C1CPU-4S-07-1131 carries a different part number, making the full model designation important during replacement.

This CPU is primarily relevant to maintenance of existing Berghof M3000/C1 installations. For a like-for-like replacement, verify the CPU suffix, hardware revision, firmware, application program, backplane arrangement, and connected I/O before commissioning.

Installation & Configuration Guide

Stage 1 — Pre-Installation

1. Record the installed CPU’s complete identification:
   • OEM P/N 2010027
   • Hardware revision
   • Firmware version
   • Serial number
2. Back up the PLC application and retained data.
3. Record CPU configuration, I/O mapping, communication parameters, and startup settings.
4. Photograph the existing installation and connector arrangement.
5. Confirm that the replacement is , not the related variant.

⚠️ Do not substitute the -1131 version solely because the main model number appears similar. Berghof assigns different OEM part numbers to the two variants.

Stage 2 — Removal

1. Place the machine in its approved maintenance state.
2. Stop the controlled process.
3. Isolate the 24 VDC control supply according to plant lockout/tagout procedures.
4. Verify the absence of hazardous voltage.
5. Apply ESD protection.
6. Label connected cables and terminals.
7. Release the CPU from its mounting/backplane connection.
8. Remove the CPU without forcing the connectors.

Stage 3 — Installation and Configuration

1. Inspect the replacement CPU for physical damage and connector contamination.
2. Confirm against the original unit.
3. Install the CPU in the correct backplane position.
4. Secure the module according to the original mechanical arrangement.
5. Reconnect all communication and system connections.
6. Restore the approved PLC application backup.
7. Verify firmware compatibility with the project.
8. Restore I/O and communication parameters.
9. Check retained variables and startup behavior before placing the machine into automatic operation.

Stage 4 — Commissioning

1. Apply 24 VDC control power.
2. Check CPU status LEDs and diagnostic information.
3. Confirm that the controller reaches the expected operating state.
4. Verify recognition of connected I/O modules.
5. Test communication with connected field devices/HMI systems.
6. Perform controlled digital and analog I/O checks where applicable.
7. Confirm alarms, interlocks, and machine sequencing.
8. Run the equipment initially under manual or low-risk conditions.
9. Record firmware, configuration, and test results for future maintenance.

Estimated replacement time: approximately 1–3 hours for a prepared like-for-like CPU replacement. Program restoration and firmware compatibility checks can extend commissioning time.

⚠️ Critical: Do not download an application created for a different CPU revision without first verifying memory allocation, firmware compatibility, I/O configuration, and startup behavior.

FAQ

What is the Berghof ?

It is a Berghof PLC CPU/controller module for the C1/M3000 automation platform. Berghof documentation identifies the exact model as , part number 2010027.

What is the OEM part number?

The documented OEM part number is 2010027. The related is separately listed as 2010037.

Is an Allen-Bradley module?

No. The exact model is associated with Berghof Automation. Some secondary industrial websites incorrectly categorize the model under A-B/Allen-Bradley inventory, but that classification is not supported by the Berghof documentation.

What voltage does the use?

A current industrial listing identifies the PLC unit as using 24 VDC. Verify the installed system’s power arrangement before energizing a replacement.

Is the same as -1131?

No. Berghof documentation assigns 2010027 to and 2010037 to -1131. Treat them as distinct orderable variants unless Berghof documentation for the specific installation confirms interchangeability.

Can the existing PLC program be transferred to a replacement CPU?

Potentially, provided the replacement hardware and firmware are compatible with the existing project. Before downloading, back up the original program and verify firmware, memory requirements, I/O configuration, and communication settings.

What condition should I specify when purchasing?

Specify New Original, New Surplus, or Refurbished/Tested. For a refurbished CPU, request confirmation that the processor boots correctly and that the unit has been tested with an appropriate Berghof system.

Verify precise compatibility with the Berghof documentation, CPU revision, firmware, and existing M3000/C1 configuration before installation.
