6ES7155-6BA01-0CN0 Siemens SIMATIC ET 200SP Interface Module Kit IM 155-6 DP HF

1.Overview of the 6ES7155-6BA01-0CN0 Siemens

The Siemens SIMATIC ET 200SP IM 155-6 PN HF is a high-performance interface module for distributed I/O systems. As the brain of the ET 200SP remote station, it seamlessly connects central controllers (such as S7-1500/1200 series PLCs) with a wide range of digital, analog, process, and communication modules in the field via Industrial Ethernet/PROFINET networks. With its excellent communication performance, compact design, and powerful integration capabilities, this module is an ideal choice for building modern, modular, and cost-effective automation solutions.

Hardware Highlights
Hot-Swap: Multiple modules can be plugged and unplugged simultaneously without losing the station, ensuring maintenance without downtime.
Reverse Polarity Protection: Built-in protection on the 24 VDC power supply provides reliable wiring.
Potential Isolation: 707 VDC withstand voltage between the PROFIBUS port and other circuits, suppressing field interference.
Tool-Free Installation: Snaps onto a 35 mm standard rail. Compact size of 50 × 117 × 74 mm saves space in the control cabinet.

Software and Diagnostics
Identification Data I&M0-I&M3: Supports online access via TIA Portal/STEP7, meeting FDA/GMP traceability requirements.
Configuration Control: Flexible station structure adjustment via user program, eliminating hardware modifications for future upgrades.
Diagnostic Interrupts, Hardware Interrupts, and Removal/Insertion Interrupts: Localize faults down to the channel level, reducing MTTR.
GSD File & S7 Module Description: Compatible with third-party masters, diagnostic frames can also be freely read via SFC13/59/52/54.
