Application fields / typical applications

The SINAMICS Intelligent Operator Panel (IOP-2) is an extremely user-friendly and powerful operator panel for SINAMICS standard drives. The SINAMICS IOP-2 supports both entry-level personnel and drive experts.

It is easy to commission standard drives thanks to the high-contrast, graphics-capable color display, the central sensor control field, the menu-based operation and the application wizards.

A drive can be largely commissioned without needing a printed parameter list – as the parameters are displayed in plain text, and explanatory help texts and the parameter filtering function are provided. Additional application wizards guide you through the commissioning of specific applications, such as conveyor systems, pumps, fans and compressors (see downloads). Commissioning can be carried out via quick commissioning or extended commissioning.

Possible applications

  • The SINAMICS IOP-2 can be used in conjunction with the SINAMICS G120, G120X, G120XA, G120P, G120C, G120D, G110M, G110D and SIMATIC ET 200pro FC-2 converters.
  • The IOP-2 can be plugged directly onto SINAMICS Control Units G120, G120P and on the compact SINAMICS G120C converter and the G120X, G120XA infrastructure converters.
  • Also available as SINAMICS IOP-2 handheld. It can also be used on distributed converters via connecting cable with optical interface.
  • With the door mounting kit, the IOP-2 can be installed, for example, in control cabinet doors (achievable degree of protection is IP55/UL type 12 enclosure).

Product properties and technical details

The SINAMICS IOP-2 offers the following main product features:


User-friendly commissioning of the SINAMICS G converters via
- Quick commissioning for simple applications
- Extended commissioning for applications with comprehensive requirements

This makes commissioning possible without knowledge of the parameter structure.

Quick commissioning without expert knowledge

Series commissioning using the clone function
User-defined parameter list with a reduced number of self-selected parameters
Simple local commissioning using the handheld version

Integrated plain text help function to locally display and remove fault messages

Reduction of downtimes due to user-friendly signaling and diagnostic functions
The diagnostics of the converter are displayed in plain text, and can be used locally on-site without documentation
The support function assists in determining and analyzing the current drive configuration

  • Determination of the drive data for the Power Module, Control Unit and IOP-2 (order number, serial number, firmware version, error statuses) and provision of the data as a two-dimensional code (data matrix/QR code).
  • Quick access via mobile devices (e.g. smartphones, tablets) to product information, documentation, FAQs, contact persons via a two-dimensional code generated on the IOP‑2 (data matrix/QR code).
  • Scanning and evaluating of a two-dimensional data matrix code using the Industry Online Support app
  • Registration of the SINAMICS converter using a QR code
  • Easy-to-establish contact with customer support via a QR code generated on the IOP-2.

Fast and direct access to product information, FAQs, downloads.

High-contrast, graphics-capable color display to show status values, such as pressure or flow in bar charts, output fields or curve displays

High degree of operator friendliness and intuitive operation
The membrane keyboard with central sensor control field and integrated control keys simplifies the input of values, navigation through lists and menus, and commissioning with wizards.
Status display with freely selectable units to specify physical values
User-specific parameter names in the status screen

Intuitive manual operation of the drive possible without additional tools; manual/automatic mode switching

  • Start/stop
  • Setpoint specification
  • Jog mode
  • Change of direction of rotation
"Manual" operating mode can be configured on a customer-for-customer basis using BiCo interconnections in the drive (p8542, p8543). The settings can be made in the SINAMICS IOP-2, "Open-loop control" menu.
The operating mode switchover at the SINAMICS IOP-2 (manual/auto using the IOP button) can be deactivated, or can be switched over by an external signal, for example, a key-operated switch (digital input of the Control Unit or via the PLC).
Yellow/black safety bar notifies users of activated safety functions
Easy cloning of specific settings of the IOP-2 user interface such as the status screen, language settings, illumination duration, date/time settings, parameter backup mode, and "My parameters". Once set, settings can easily be transferred to many other IOP-2s.

Available user interface languages: German, English, French, Italian, Spanish, Portuguese, Dutch, Swedish, Russian, Czech, Polish, Turkish, Finnish and Simplified Chinese.

Update of device functionality (e.g. languages, firmware) via USBCan be flexibly expanded

Preconditions / dependencies

The SINAMICS IOP-2 with firmware V2.4.x can be used with the SINAMICS converters G120 (CU240B-2, CU240E-2, CU250S-2), G120X, G120XA, G120P (CU230P-2), G120C, G120D (CU240D-2, CU250D-2), G110M, G110D and SIMATIC ET 200pro FC-2 with a SINAMICS Pool firmware version from V4.4 to V4.7 SP10 (G110D with GP Pool firmware V3.6; G120X/ XA with V4.7 SP11 OA V1.

A detailed overview of the supported drive systems and their associated firmware releases can be found in entry ID 67273266. The IOP firmware ≥ V2.0 can only be used on the IOP-2 device hardware.

Known restrictions

Functions no longer supported

The following functions of its predecessors (6SL3255-0AA00-4Jx1, x = A/C) are no longer supported by the IOP-2:

  • Commissioning, control, diagnostics, monitoring of the following SINAMICS converters:
    • SIMATIC ET 200pro FC (GP Pool)
      The product has been replaced by its successor SIMATIC ET 200pro FC‑2.
    • SINAMICS S110 (CU305)

A first generation IOP with firmware version V1.6 SP2 will remain available for these drive systems for a transitional period (see announcement of product phase-out of the first IOP generation).

New commissioning concept as of IOP-2 V2.3

The new commissioning concept for SINAMICS G converters G120, G120X, G120XA, G120P, G120C, G120D, G110M and SIMATIC ET 200pro FC-2 will only be supported as of SINAMICS Pool firmware version V4.7 SP3. For converters with older firmware versions, V2.3 automatically provides the wizards from IOP-2 V2.2.

Extended commissioning currently does not support dialog-guided configuration of application functions such as PID and Boost. The known application wizards from IOP-2 V2.2 can be made accessible again by reloading on IOP-2. Please contact your Siemens contact person in this regard (intranet).


The IOP-2 supports the following certificates: CE, UL/CSA, C-Tick/RCM, EAC, KC.

Announcement of product phase-out of the first IOP generation

The phase-out (P.M400) of the first IOP generation was announced on October 1, 2017. Product cancellation (P.M410) was declaired on April 1, 2019. No more additional functions are planned for the first IOP generation. Additional functions will only be implemented on the basis of the IOP-2.
