Communication Architecture

Interface roles at a glance

Function-focused view

ETH

Ethernet layer

Provides onboard TCP/IP communication together with integrated web-server, SNTP and IEC 60870-5-104 capabilities.

Serial layer

The two serial interfaces support the programming and serial communication functions listed for the processor module.

Fieldbus access

The FBP interface provides the fieldbus connection point identified for the AC500 processor architecture.

System Fit

Installation, accessories & migration checkpoint

Terminal base

R0271 PM59x-ETH processor modules use the corresponding TB5x1-ETH(-XC) terminal-base family with R0270 order numbering.

Battery

TA521 lithium battery · 1SAP180300R0001

Memory

MC502 memory card · 1SAP180100R0001

Selection check

Match the installed processor order code and terminal-base arrangement before removing an existing CPU.

Different from standard product blocks

V2 → V3 project checkpoint

ABB's AC500 conversion guidance identifies differences in project configuration when moving from AC500 V2 to V3, including Modbus TCP memory structure and addressing. A hardware change should therefore be treated as a project-migration task rather than only a physical CPU exchange.

Application & Fault Search

When buyers usually search for this module

Controller CPU replacement

Used when an installed AC500 processor module requires like-for-like identification before a maintenance exchange. Downtime risk · controller availability

Ethernet communication fault

Common search context when the controller remains unavailable through the existing Ethernet communication path and the processor order code needs to be matched. Downtime risk · network-dependent control communication

Serial / Modbus issue

Relevant when existing programming, Modbus or CS31 communication depends on the processor's serial interface configuration. Downtime risk · field communication interruption

Product & sourcing support

Service coverage across Asia, Europe, North America, South America and the Middle East.

FAQ

Buyer questions before replacement

Can PM591-ETH be treated as the same hardware architecture as PM591-2ETH?

No. The two variants use different interface arrangements and the PM591-2ETH has its dedicated TB523-2ETH terminal-base requirement. Match the installed processor variant before ordering.

What should be checked before exchanging an installed processor?

Check the installed order code, terminal-base arrangement and existing project configuration. For a V2-to-V3 migration, review the application conversion requirements rather than treating the change as a physical module swap only.

Why can an Ethernet fault lead to a PM591-ETH replacement search?

The processor provides the onboard Ethernet communication layer, so a controller communication failure can lead maintenance teams to identify the installed CPU and compare its exact order code before sourcing a replacement.

Can AMIKON arrange testing before shipment?

Inspection and functional testing can be arranged where applicable, followed by protective export packaging and the applicable AMIKON after-sales process.

What information should be included in a quotation request?

Send the part number, quantity, destination, required date and machine/system model so the sourcing team can match the request efficiently.
