What It Is and What It Does
The Siemens 6ES7151-3AA00-0AB0 is a SIMATIC DP interface module IM151-3 PROFINET for the ET200S distributed I/O system. It connects up to 63 power, electronic, or motor starter modules (up to 2 m width) to a PROFINET IO network via two RJ45 ports at 100 Mbit/s full duplex. The module handles 256 bytes each of input and output data.
Sourcing and Lifecycle
Marked as current lifecycle — no phase-out or discontinuation date. This is an active catalogue line, sourced through standard Siemens distribution. Quoted to order against an RFQ.
Network and Diagnostics Fit
Two RJ45 ports with automatic transmission rate detection (100BASE-TX, full duplex). Diagnostics are built in: group error SF (red), bus fault BF (red), and LINK (green) LED per port. Supports ARP, Ping, and SNMP for network management. The module draws up to 200 mA from the 1L+ supply voltage and dissipates 2 W typ. Isolation tested at 500 V DC between Ethernet and electronics.
