Description

Siemens 6GK1543-1AA01 is the SIMATIC NET CP 5431 FMS/DP communications processor for supported SIMATIC S5-115U/H, S5-135U and S5-155U/H systems. Siemens application documentation shows it as the passive S5 communication processor in a PROFIBUS FDL exchange with an S7-300 CP 342-5 partner.

A legacy CP 5431 processor for PROFIBUS communication in SIMATIC S5 systems.

The 6GK1543-1AA01 The module preserves legacy PROFIBUS FMS, DP and FDL communication paths in installed S5 systems. Replacement requires the original rack position, interface addressing, bus parameters and communication project, not only the same front-panel appearance. Existing configuration files and partner details should be secured before removing the processor.

Product Applications

PRODUCT OPERATING PATH

Connect S5 to PROFIBUSProvides the communication processor for supported S5 controller racks.

Exchange FDL dataSupports configured layer-2 services such as the documented SDA example.

Maintain legacy cellsKeeps an established S5 communication node operating without redesign.

Configuration Advantages

MODEL-SPECIFIC
SELECTION VALUE

The complete model identity and its documented interfaces are checked together before replacement or integration.

S5 integration

Designed for documented SIMATIC S5 controller families.

FMS and DP role

Supports legacy PROFIBUS communication services used by installed projects.

Processor offload

Handles network communication separately from the S5 CPU.

Exact-project continuity

Using the same order number helps preserve rack and configuration compatibility.

FAQ

Q1. Which controller families use 6GK1543-1AA01?

Siemens identifies the CP 5431 for supported S5-115U/H, S5-135U and S5-155U/H systems.

Q2. What network is handled by 6GK1543-1AA01?

It is a PROFIBUS FMS/DP communications processor.

Q3. Which FDL service is shown with 6GK1543-1AA01 in the Siemens example?

The application example uses SDA through free layer 2 access.

Q4. Why must the rack address be recorded before replacing 6GK1543-1AA01?

S5 communication processors depend on the configured slot, interface number and project addressing.

Q5. Can a modern Ethernet CP directly replace 6GK1543-1AA01?

No. The bus protocol, rack interface and engineering environment are different.

Q6. What project files are valuable when sourcing 6GK1543-1AA01?

Retain the CP configuration, PROFIBUS parameters, partner definitions and the S5 program archive.
