The Siemens WinCC/SES Sequence Execution System is designed for the sequential control of recipe and sequence-based processes in production. WinCC/SES is especially suitable for production plants in which dosing, mixing and material transport are important process actions. Sequence controls can be structured with a high degree of flexibility, with the production steps being defined in a clear configuration interface and freely combined to form individual process sequences. In addition both the step sequences and the parameters can be modified online during production runs.

Combination of automatic step sequence with manual fine adjustment of the production sequences (e.g. if behaviour of natural raw materials fluctuates)
SES allows flexible paths through the production and is thus an enabler for even utilization of the individual production plants
Increased quality due to efficient operations management
SES fulfils the real-time requirement because the steps run in the PLC
High availability due to the execution of the step sequencer in the PLC
