Features:
- The 512 kB program-memory configuration executes IEC 61131-3 machine logic while preserving the I/O and supply identity encoded by 1SAP121200R0071.
- Onboard resources combine 8 digital inputs and 6 transistor outputs with Ethernet and RS-485 communication for a compact controller that can be extended by up to ten compatible I/O modules.
- The transistor output stage, 24 V DC supply and separately selected terminal blocks must be matched to the installed wiring before the CPU is commissioned.
ABB identifies PM556-TP-ETH 1SAP121200R0071 as a AC500-eCo programmable logic controller with 512 kB program memory, integrated Ethernet and 8 digital inputs and 6 transistor outputs. The transistor-output configuration and 24 V DC supply are fixed by the complete order code, so nearby PM554, PM556, PM564 and PM566 variants are not interchangeable by housing alone. The CPU supports IEC 61131-3 programming through Automation Builder, an integrated RS-485 COM1 port and an optional second serial interface. Ethernet variants provide approved programming and communication services including Modbus TCP, HTTP, FTP, SNTP, DHCP and UDP. Up to ten S500 or S500-eCo I/O modules may be attached within the documented system limits. Pluggable terminal blocks and optional clock, serial or memory accessories are selected separately. A replacement check therefore covers the full article number, supply, output type, onboard I/O, terminal style, firmware and retained application project.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Use the 512 kB project target and confirm library, firmware and remanent-data requirements before download. A PM554 project may migrate, but the engineering project must still be validated.
Match the six onboard transistor-output assignments to compatible 24 V DC loads and protective circuits. Retain the documented common arrangement and output grouping.
If the project uses PM556 SMTP or web visualization, preserve server addresses, credentials and network settings through the approved Automation Builder workflow.
