SIMOTION

SIMOTION is a family of motion control systems designed for high-performance automation, integrated machine control, and robotics. It combines motion control, logic, HMI integration, and drive technology into a single platform to address applications in packaging, printing, textile, and robotics industries. The product line is developed to interoperate with other Siemens automation offerings and third-party components across manufacturing environments.

Overview

SIMOTION is engineered as an integrated motion and automation platform combining programmable logic, motion control, and human–machine interface capabilities. It is positioned alongside other industrial control products from Siemens, intended to bridge machine-level coordination and plant-level orchestration. The system targets applications that require synchronized multi-axis control, high-speed interpolation, and coordinated robotics tasks while maintaining compatibility with fieldbuses and industrial Ethernet solutions.

History and Development

The development of this motion platform occurred within the industrial automation expansion of Siemens in the late 1990s and 2000s, coinciding with advances in deterministic Ethernet and distributed control architectures. Its evolution reflects trends in the automation industry such as the adoption of PROFINET, modular drive systems, and integrated safety standards like IEC 61508 and ISO 13849. Over successive generations, firmware and engineering tool updates introduced support for modern PLCopen motion function blocks, enhanced interpolation algorithms, and tighter integration with HMI products such as SIMATIC HMI.

Architecture and Components

The platform architecture is modular, comprising CPU modules, motion controller cores, I/O modules, and drive interfaces. Central processing units implement task scheduling and interpolation, while dedicated motion processors handle servo and position control loops. The system interfaces with SIMATIC S7 controllers, distributed I/O like ET 200, and drive families such as SINAMICS. Communication layers include support for PROFINET, EtherCAT, and legacy buses like PROFIBUS DP. Safety-related components integrate with safety controllers compliant with standards adopted by industry certification bodies like TÜV Rheinland.

Features and Functionality

Key functional elements include multi-axis coordinated motion, camming and gearing functions, kinematics for gantry and robotic systems, and electronic gearing. The platform supports high-speed interpolation (linear, circular, spline) and advanced trajectory generation for applications requiring precise path control. Diagnostic and commissioning features include waveform recording, oscilloscope-like tracing, and parameter versioning to aid maintenance teams familiar with tools from Siemens and partners. Security and access control align with guidelines from organizations such as ISA and standards like IEC 62443 for automation cybersecurity.

Applications and Industry Use

Adoption spans industries requiring precise motion coordination: packaging machines in facilities run by firms that partner with ABB and KUKA integrators; printing presses alongside equipment from Heidelberg; textile production lines and weaving machinery produced by companies similar to Tsudakoma; and glass processing plants using CNC apparatus comparable to Husqvarna. Applications also include extrusion lines for plastics involving suppliers like KraussMaffei, pick-and-place robots in electronics assembly cells with companies such as Foxconn, and airport baggage handling systems collaborating with integrators akin to Beumer Group. System integrators implement SIMOTION in projects meeting standards from bodies like ISO and regional authorities including CE conformity processes.

Programming and Configuration

Engineering is performed with toolchains that merge PLC programming and motion setup into unified environments. Programming languages follow IEC 61131-3 standards with support for function block diagrams, structured text, and ladder logic, while motion-specific libraries implement PLCopen-compatible function blocks. Configuration tools integrate with HMI design suites such as WinCC and simulation platforms used by integrators collaborating with firms like Rockwell Automation for concept validation. Parameterization of servo drives, tuning of PID loops, and configuration of fieldbus mappings are supported through vendor-specific utilities and standardized file formats for interchange.

Performance, Standards, and Compatibility

Performance metrics are expressed in terms of interpolation cycle times, servo update rates, and synchronization jitter, benchmarked against expectations in industrial automation white papers published by entities like VDE and IEEE. Compatibility matrices document interoperability with drive families such as SINAMICS and third-party axes conforming to CiA profiles. Compliance efforts include adherence to safety standards like IEC 61508 and functional safety practices endorsed by certification organizations including TÜV SÜD. Integration with industrial networking standards such as PROFINET and EtherCAT ensures real-time determinism for complex multi-axis and multi-device topologies.
