Core Functions & Advantages

6GK1143-0AA01 expands Ethernet communication capacity for SIMATIC S5 controllers and removes the restriction that traditional S5 devices only support local programming. Equipped with an independent communication processing chip, 6GK1143-0AA01 processes communication tasks independently without occupying operation resources of S5 CPU, so the stability of control programs can be guaranteed. The hardware can be installed on all mainstream SIMATIC S5 racks, and system upgrading does not require replacing the whole control system. The module supports two transmission modes including periodic data exchange and on-demand communication, which adapts to process data collection, remote program debugging and other scenarios. Reliable continuous operation meets the demand of non-stop production for upgraded metallurgy and power production lines.

Operation Guide

Step 1: Under power-off status, insert 6GK1143-0AA01 steadily into the idle slot of SIMATIC S5 rack. Confirm full engagement with backplane connector and lock the module buckle.

Step 2: Connect external 15V DC power cables to module terminals, and wire AUI Ethernet cable or external AUI transceiver.

Step 3: Switch on power and check module LED indicators to confirm normal power supply without hardware alarms.

Step 4: Complete parameter configuration for 6GK1143-0AA01 through corresponding SIMATIC programming software, configure station address, communication protocols and data exchange areas.

Step 5: Download configuration parameters to the module, establish network connection and test data sending and receiving between PLCs or between PLC and host computer.

Step 6: Keep continuous trial run and observe communication status indicators to ensure sustained and stable data transmission.

Working Principle

6GK1143-0AA01 acts as an independent communication gateway to forward data between SIMATIC S5 backplane bus and SINEC H1 Ethernet. S5 CPU transmits outbound data to the cache area of 6GK1143-0AA01 via backplane bus. The onboard communication processor encapsulates data packets according to AP/TF protocols and transmits data through AUI interface. Instructions and data issued from external network will be decapsulated by the module and delivered to S5 CPU through backplane bus. The whole data interaction process is scheduled autonomously by the processor carried by 6GK1143-0AA01, realizing data isolation between control layer and network layer.
