Product information
01
 

Processor Memory, Onboard I/O & Interfaces

Compact CPU architecture with 512 kB program memory, Ethernet and transistor I/O.

System role

PM556-TP-ETH combines an ARM-based controller, integrated Ethernet and fixed digital I/O in the AC500-eCo form factor for stand-alone machine programs.

Expanded program capacity The 512 kB program memory is four times the capacity of the PM554 class and is intended for more complex compact-machine applications.
Built-in machine I/O Eight digital inputs and six 24 V DC transistor outputs support direct compact control without a separate base CPU I/O module.
Serial connectivity COM1 supports programming, Modbus, serial ASCII and CS31 master use; an optional second RS-485 interface can be fitted.
Execution profile ABB specifies cyclic, time-controlled and multitasking execution with a RUN/STOP switch and password protection capability.

Terminal Blocks, Ethernet & Legacy-System Planning

A reliable PM556-TP-ETH replacement must preserve the 24 V DC transistor-output configuration, plug-in terminals, controller program and communication settings.

01
Pluggable I/O terminalsThe CPU uses separately selected pluggable I/O terminal blocks; confirm the installed block style and conductor routing.
02
Ethernet engineeringThe onboard Ethernet interface supports networked programming and application communication. Preserve IP settings and network dependencies during replacement.
03
COM1 migrationDocument whether RS-485 is used for Modbus, ASCII, programming or CS31 master communication before moving the application.
04
Optional COM2 hardwareA second serial interface requires the matching ABB option hardware; it is not implied by the PM556-TP-ETH order code.
05
Central expansionABB permits up to ten I/O modules in the documented AC500-eCo configuration, subject to system power and module rules.
06
Classic lifecycleABB lists this order code as Classic and gives no specific migration device in the latest data-sheet row; do not claim an automatic successor.

Buyer Questions for ABB PM556-TP-ETH

Program capacity, terminal blocks, communications, lifecycle and replacement evidence.

Q01

What program-memory capacity does ABB PM556-TP-ETH provide for an existing machine project?

ABB PM556-TP-ETH provides 512 kB of Flash EPROM program memory. Verify the saved application, retained data use and optional accessories before exchanging the CPU.

Q02

Which onboard field points must be matched when replacing ABB PM556-TP-ETH?

Match eight 24 V DC digital inputs and six 24 V DC transistor outputs. Relay-output or mixed-analog AC500-eCo CPUs are not wiring-equivalent replacements.

Q03

How can ABB PM556-TP-ETH communicate with programming and field devices?

ABB PM556-TP-ETH has onboard Ethernet and an RS-485 COM1 interface. COM1 can be used for programming, Modbus, serial ASCII or CS31 master communication; COM2 requires optional hardware.

Q04

Does ABB still classify ABB PM556-TP-ETH as an Active CPU?

No. ABB's latest PM55x/PM56x data sheet lists order code 1SAP121200R0071 in the Classic phase, meaning legacy availability may continue but it is not recommended for new installations.

Q05

Has ABB named a direct migration device for ABB PM556-TP-ETH?

ABB leaves the possible migration-device field blank for PM556-TP-ETH in the latest data sheet. Any AC500-eCo V3 migration therefore requires an engineering check of program, I/O, terminals and communications.

Q06

Which records should accompany an ABB PM556-TP-ETH quotation request?

Provide order code 1SAP121200R0071, nameplate and terminal photos, installed options, application backup status, Ethernet and serial use, quantity, destination and delivery date.

Transaction Cases

Sincere Cooperation, Long-Term Trust

RussiaCASE 01

A Russian customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.

IndiaCASE 02

An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.

VenezuelaCASE 03

A Venezuelan customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
