Brand	Siemens
Model	6ES7151-1AB02-0AB0
Product Type	Fiber-optic PROFIBUS DP interface module
Core Function	Connects an ET 200S station to a PROFIBUS DP master over optical fiber
Compatible Series	SIMATIC ET 200S / IM151-1 FO STANDARD

Optical DP connection

Links the ET 200S station to a PROFIBUS DP master through the fiber-optic interface.

128-byte I/O areas

Supports up to 128 bytes of input addresses and 128 bytes of output addresses.

Line network planning

Integrated optical interfaces are arranged as a fiber-optic line in Siemens installation guidance.

Product Overview

6ES7151-1AB02-0AB0 is the IM151-1 FO STANDARD interface module for a SIMATIC ET 200S remote I/O station. It exchanges data with a PROFIBUS DP master through an integrated fiber-optic interface.

Siemens identifies this order number as the earlier FO STANDARD version with a maximum of 128 bytes for inputs and 128 bytes for outputs. The station optical line and power wiring must follow the ET 200S operating instructions.

Ordering focus: Match the exact IM151-1 FO generation, 128-byte station address allocation, optical connectors and 24 V supply wiring.

Key Functions

ET 200S optical interface

The module connects the ET 200S backplane and I/O station to the DP master by fiber-optic cable.

Station data exchange

The earlier 6ES7151-1AB02-0AB0 version supports up to 128 bytes each for input and output addressing.

Optical-line wiring

Siemens specifies simplex connectors, a plug adapter and duplex optical cable for the interface.

Compatibility & Ordering Notes

Before ordering 6ES7151-1AB02-0AB0: Check the exact interface-module generation and ET 200S configuration. The 6ES7151-1AB02-0AB0 station is limited to 128 input bytes and 128 output bytes; verify both address allocations before replacement.

Station and optical-line checks

• Confirm the ET 200S station uses the IM151-1 FO STANDARD fiber-optic DP interface.
• Check the programmed input and output address spaces against the 128-byte limits.
• Confirm simplex connectors, plug adapters and duplex optical cable match the installed line.
• Check 24 V power and loop-through terminals and blank the unused end optical interface.
