Siemens 6GK1143-0AA00 Communications Processor

This communications processor handles network data exchange for SIMATIC S5 systems. It connects the controller to industrial Ethernet networks for plant-wide communication. Therefore, this component enables remote monitoring and data acquisition applications.

Physical Dimensions and Weight Specifications

The Siemens 6GK1143-0AA00 occupies one standard slot in the S5 rack. Its housing measures 233 mm in depth for backplane connectivity. The module weighs approximately 0.52 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The Siemens 6GK1143-0AA00 provides one AUI port for Ethernet transceiver connection. A second 20-pin backplane connector links to the S5 CPU bus. The front panel carries LED indicators for network activity and status. Hence, operators can monitor communication health at a quick glance.

Component Count and Communication Protocol

This communications processor contains one main board with a dedicated network controller. The board holds 128 KB of buffer memory for message queuing. You will also find an Ethernet controller chip for frame processing. An onboard microcontroller handles protocol conversion and diagnostics.

Energy Storage and Power Consumption

The Siemens 6GK1143-0AA00 draws 250 mA from the 5V backplane supply. A small electrolytic capacitor maintains buffer memory for 10 milliseconds. This short storage protects message data during brief power dips. The module does not require a backup battery for normal operation.

Network Performance and Diagnostics

The processor handles up to 200 frames per second on the Ethernet network. It supports TCP/IP and ISO transport protocols for flexibility. Users can read diagnostic data via the S5 programming software. This feature reduces troubleshooting time for network faults.
