6ES7155-6BA01-0CN0 Siemens SIMATIC ET 200SP Interface Module Kit IM 155-6 DP HF
The Siemens 6ES7155-6BA01-0CN0 is a compact, cost-effective PROFINET interface module from the SIMATIC ET 200SP distributed I/O system, designed to connect up to 64 I/O modules (max. 32 per station) directly to a PROFINET IO network. As the basic variant (BA) of the IM 155-6 PN series, this module provides essential connectivity for small to mid-sized automation tasks—ideal for machinery, packaging lines, HVAC systems, and process skids where space, simplicity, and reliability are critical.
Featuring an integrated 2-port PROFINET switch, the 6ES7155-6BA01-0CN0 enables daisy-chain wiring without external switches, reducing cabling complexity and cabinet space. It supports real-time communication with S7-1200, S7-1500, and other PROFINET controllers, and integrates seamlessly into TIA Portal (Totally Integrated Automation Portal) for fast hardware configuration, diagnostics, and firmware updates. With support for shared device functionality and system redundancy (with compatible CPUs), it offers future-proof scalability even in its basic form.
