Siemens 6ES5560-8AA11 | Individual Control Module

Intelligent Co-Processor for SIMATIC S5 Systems

The 6ES5560-8AA11 individual control module serves as an intelligent co-processor for large-scale SIMATIC S5-135U and S5-155U multiprocessor systems. This module offloads demanding computational tasks from the main CPU, effectively reducing overall scan cycle times. It communicates with the host system through an IM308 interface module, exchanging data via dual-port RAM. Therefore, this module provides an excellent solution for enhancing the performance and extending the service life of legacy S5 installations.

Autonomous Processing and Parallel Execution

The 6ES5560-8AA11 features an independent processor and dedicated firmware. It executes complex control algorithms such as multi-loop PID, position regulation, and high-speed counting without burdening the host CPU. Furthermore, this module runs its tasks in parallel with the main CPU’s scan cycle. Consequently, this parallel processing architecture delivers substantial improvements in system responsiveness and control accuracy for complex automation tasks. Users can thus achieve faster cycle times and more precise control.

System Integration and Application Scenarios

Users integrate the 6ES5560-8AA11 into S5-135U or S5-155U racks through an IM308 interface module. This module is specifically designed for retrofitting applications. It allows users to upgrade control electronics while keeping existing power sections and motors in place. Furthermore, this “distributed intelligence” architecture ensures that even if one module fails, the remaining independent modules continue their operations uninterrupted. This design proves especially valuable in applications like tension control, fast positioning, and multi-variable temperature regulation.

Diagnostics and Maintenance

This co-processor features comprehensive diagnostic capabilities for straightforward troubleshooting. LED indicators on the front panel display RUN, STOP, ERROR, and BUS FAULT status. Consequently, maintenance personnel can quickly identify module health and communication issues. The 6ES5560-8AA11 also supports parameterization via software tools for simplified configuration.
