NEW 6ES7155-6AU01-0CN0

The 6ES7155-6AU01-0CN0 is a PROFINET interface module belonging to Siemens’ SIMATIC ET 200SP series, specifically the IM 155-6 PN ST type. It serves as a central interface for connecting peripheral modules in distributed automation systems, enabling communication via the PROFINET protocol.

This module supports a maximum of 32 peripheral modules and 16 ET 200AL modules, making it suitable for medium-sized to larger distributed setups. It features a 24V DC power supply with a voltage range of 19.2V to 28.8V DC, and includes protection mechanisms such as reverse polarity protection and short-circuit protection to enhance operational reliability.

In terms of communication, it utilizes a PROFINET interface with integrated switch functionality (via compatible bus adapters) to facilitate network connectivity. The module supports hot swapping of peripheral modules when used with appropriate hardware, allowing for maintenance and replacement without interrupting the entire system operation.

Configuration and commissioning are typically performed using Siemens’ TIA Portal software, ensuring seamless integration into the SIMATIC automation ecosystem. The 6ES7155-6AU01-0CN0 is designed for industrial environments, offering robust performance in applications such as manufacturing, process control, and machinery automation where distributed I/O architecture is required.
