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. There is a basic commissioning wizard for general commissioning.

Possible applications

  • The SINAMICS IOP-2 can be used in conjunction with the SINAMICS G120, G120P, G120C, G120D, G110M, G110D and SIMATIC ET 200pro FC-2 converters.
  • It can be mounted directly on SINAMICS G120, G120P Control Units – and on the SINAMICS G120C compact converter.
  • Available as SINAMICS IOP-2 handheld. It can also be used on distributed converters via connecting cable with optical interface.
  • It can be mounted in the control cabinet door using a door mounting kit (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:

Series commissioning using the clone functionQuick commissioning without expert knowledge
User-defined parameter list with a reduced number of self-selected parameters

Simple commissioning of standard applications using wizards, it is not necessary to know the parameter structure.

Application wizards that can be subsequently loaded are available on the Internet.

Simple local commissioning using the handheld version

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

Fast diagnostics using plain text display on-site

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 means

  • Operating mode switchover between manual and automatic modes
  • 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).

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

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

Known restrictions


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).


The IOP-2 provides the following certifications: CE, UL/CSA, C-Tick/RCM, EAC.
At the moment, there is not yet a KC certificate for the IOP-2 (certification of machines and plants in Korea). The certification is in progress. As soon as we receive the certificate, this will be communicated.

Announcement of product phase-out of the first IOP generation

The first IOP generation has reached the milestone product phase out (P.M400) on October 1st, 2017. The product cancellation (P.M410) is scheduled for one year later 10/01/2018. No more additional functions are planned for the first IOP generation. Additional functions will only be implemented on the basis of the IOP-2.
