Spare part designation and lifecycle status
The 6ES7151-3BA50-0AB0 is explicitly designated a spare part in the SIMATIC DP line, serving as the IM 151-3 PN HS interface module for the ET 200S distributed I/O system.
PROFINET performance and I/O capacity
This interface module supports PROFINET IO with a maximum transmission rate of 100 Mbit/s and includes two RJ45 ports for line or star topology connections. It handles 200 bytes each of process input and output data, which sets the ceiling for the number and type of ET 200S electronic modules the head station can address without exceeding the bus cycle budget. Isochronous mode is supported, enabling deterministic equidistant cycle synchronization for motion-control and high-speed process applications where jitter must stay below the bus cycle.
Diagnostics and status indication
Onboard diagnostics include a group error SF (red) LED, bus fault BF (red) LED, and a LINK (green) LED per RJ45 port, plus a 24 V supply monitoring LED — enough to localise a fault to the backplane bus, the Ethernet link, or the field-side supply without a programming device. Galvanic isolation exists between the Ethernet interface and the electronics, but not between the backplane bus and the electronics, nor between the supply voltage and the electronics — a distinction that matters when planning surge protection zones in the cabinet.
Power budget and physical fit
The module draws up to 350 mA from the 24 V field supply (1L+) and 0.7 A from the 5 V backplane bus, with a typical power loss of 6 W — the backplane current is the tighter constraint when chaining multiple active bus modules on one ET 200S segment.
