Siemens 6GK1143-0AA01 Interface Module

The Siemens 6GK1143-0AA01 interface module connects SIMATIC S5 controllers to Industrial Ethernet networks. This module handles data exchange between S5 CPUs and higher-level management systems. It mounts directly into any S5-115U or S5-135U rack slot. You can use this module as a direct replacement for failed communication units.

Detailed Technical Specifications

The Siemens 6GK1143-0AA01 interface module measures 250 mm in length. Its width reaches 160 mm across the main body. The total height goes up to 50 mm with all components installed. This unit weighs approximately 0.62 kilograms for secure mounting.

Key hardware parameters include:

Complete Model: Siemens 6GK1143-0AA01
Component count: 112 individual electronic parts
Connector ports: One 9-pin SUB-D (Ethernet AUI)
Network interface: 10 Mbps CSMA/CD (IEEE 802.3)
Protocols: ISO transport layer 4, TCP/IP
Energy storage: Six aluminum capacitors (220 µF each)
Mounting system: Two rear locking levers
PCB layers: Six-layer high-speed construction
Address range: Up to 254 S5 stations per segment
Diagnostics: 8 LED status indicators
Memory: 16 KB dual-port RAM for data exchange

The Siemens 6GK1143-0AA01 interface module stores moderate residual charge after power-off. Therefore, technicians must wait thirty seconds before handling the module. The AUI port requires an external transceiver for twisted pair or fiber connection. Moreover, the module supports both SEND/RECEIVE and FETCH/WRITE services.

Application and Installation

The Siemens 6GK1143-0AA01 interface module slots into any S5 rack alongside the CPU. It requires an external AUI-to-twisted-pair transceiver for standard Ethernet cabling. This module enables S5 controllers to communicate with SIMATIC S7 and PC-based systems. Consequently, you can integrate legacy S5 machines into modern factory networks.

Communication and Reliability

This module buffers incoming telegrams in its dual-port RAM. The Siemens 6GK1143-0AA01 handles up to 16 simultaneous connections without performance degradation. You configure the module using standard S5 function blocks (FB 180 to FB 195). Therefore, adding Ethernet connectivity requires minimal changes to existing S5 programs.

Always power down the rack before inserting or removing this module. Connect the AUI cable securely to the 9-pin port. The module features LED indicators for link status, activity, and fault conditions. Furthermore, its conformal coating protects against dust and light moisture.
