6ES7154-8AB01-0AB0 IM 154-8 PN/DP CPU

Siemens 6ES7154-8AB01-0AB0 is the SIMATIC ET 200pro IM 154-8 PN/DP CPU with 384 KB work memory, an integrated PROFINET interface and an integrated PROFIBUS DP master/slave interface. The field-oriented enclosure is rated IP65/67 when assembled with the required connection module. The CPU uses a SIMATIC Micro Memory Card and is engineered from STEP 7 V5.5. Before replacement, the controller project, firmware, memory card, station modules, PROFINET identity and PROFIBUS operating role must all be matched to the installed system.

Product Overview

Siemens 6ES7154-8AB01-0AB0 is the SIMATIC ET 200pro IM 154-8 PN/DP CPU with 384 KB work memory, an integrated PROFINET interface and an integrated PROFIBUS DP master/slave interface. The field-oriented enclosure is rated IP65/67 when assembled with the required connection module. The CPU uses a SIMATIC Micro Memory Card and is engineered from STEP 7 V5.5. Before replacement, the controller project, firmware, memory card, station modules, PROFINET identity and PROFIBUS operating role must all be matched to the installed system.

Runs the control program directly in the ET 200pro station without a separate central CPU. Combines PROFINET controller communication with a separate PROFIBUS DP master or slave interface. The assembled station provides IP65/67 protection for machine-level decentralized installation.

Ordering focus: confirm the complete AB01 CPU article number, 384 KB memory class, firmware, STEP 7 hardware entry, SIMATIC Micro Memory Card, connection module, ET 200pro station layout, PROFINET parameters and PROFIBUS master or slave configuration before ordering.

Match the AB01 CPU, firmware, memory card, connection module, ET 200pro station layout and both network configurations.

Compatibility & Ordering Notes

Before ordering 6ES7154-8AB01-0AB0: confirm the complete AB01 CPU article number, 384 KB memory class, firmware, STEP 7 hardware entry, SIMATIC Micro Memory Card, connection module, ET 200pro station layout, PROFINET parameters and PROFIBUS master or slave configuration before ordering.

Compatibility Checklist

• Use in a compatible SIMATIC ET 200pro station with the required connection hardware.
• Engineer the exact AB01 CPU with STEP 7 V5.5 or a later supported release.
• Retain the installed SIMATIC Micro Memory Card and verify its project contents.
• Back up the PROFINET device name, IP parameters, topology and controlled IO devices.
• Preserve the PROFIBUS master or slave role, address, transmission rate and station data.
• Keep the configured input and output address allocation within the documented limits.
• Confirm seals, connectors and station assembly before relying on the IP65/67 rating.
