PM5630-2ETH is an AC500 V3 standard processor module designed for the TB56xx-2ETH terminal-base platform. Active revision 3 article 1SAP131000R0378 provides 8 MB memory, two independent onboard Ethernet interfaces and integrated serial and CAN connectivity.

The processor module includes a display and memory-card slot but requires a compatible terminal base to form a complete controller. Revision 3 retains the function of revision 2 while introducing specific firmware and Automation Builder requirements.

• Runs AC500 control applications with 8 MB memory.
• Provides two independent RJ45 Ethernet TCP/IP interfaces for separate network assignments.
• Supports Modbus TCP, web-server functions, IEC 60870-5-104 or selectable Ethernet-based protocols in the documented configuration.
• Adds one RS-232/485 interface and one CAN interface through the matching terminal-base system.
• Uses the integrated display for controller status and service interaction.
• Operates on 24 V DC with a typical module-only current of 110 mA.

• Mounts on the specified TB56xx-2ETH terminal base, which provides the controller connection environment.
• Supports architectures that keep two Ethernet networks logically separated or use the interfaces for different protocols.
• Can connect serial and CAN communication through the installed controller hardware configuration.
• Requires consistent firmware across revision 2 and revision 3 processors used in the same upgraded application.
• Must be engineered with Automation Builder 2.6.0 or later when revision 3 hardware is introduced.

• AC500 control stations that require two independently configured Ethernet networks.
• Process or infrastructure controllers using Modbus TCP or IEC 60870-5-104.
• Machines that combine Ethernet, serial and CAN communication in one CPU assembly.
• Revision 2 controller replacement after the application and firmware are upgraded for revision 3.
• Standard AC500 V3 systems built on a compatible TB56xx-2ETH terminal base.

Which article identifies the active PM5630-2ETH revision?

Active revision 3 is article 1SAP131000R0378; revision 2 R0278 is in the Classic phase.

Can the processor operate without a terminal base?

No. PM5630-2ETH requires a compatible TB56xx-2ETH terminal base to form the controller assembly.

What software baseline applies to revision 3?

ABB requires Automation Builder 2.6.0 or later and boot/CPU firmware V3.6.x or later.

Can revision 3 be downgraded below firmware V3.6.0?

No. The revision 3 hardware cannot be used with an earlier firmware level.

Are the two Ethernet ports only an unmanaged switch?

They are documented as two independent onboard Ethernet TCP/IP interfaces, allowing separate interface assignments.

What should be retained before an R0278-to-R0378 exchange?

Retain the project, firmware, terminal-base model, both Ethernet configurations, serial/CAN settings and application backup.
