Intelligent operator panel for direct connection to the drive

for local operation, monitoring, setup, diagnostics, service


The mounted IOP-2 Intelligent Operator Panel and its remote handheld version allow fast local setup, fault diagnostics and intuitive operation of SINAMICS G120 drive series and simplifies the adjustment of settings during operation. It features an intuitive central multifunctional sensor control wheel.


There are three methods of using the IOP-2: Directly plugging it into the control unit of the drive, mounting in the door for operation outside the control cabinet, and as an IOP handheld unit for wired operation in difficult-to-access locations.


The IOP-2 is available as an additional option for the SINAMICS drive series G120G120X, G120C, G120D, G110M and SIMATIC ET 200pro FC-2

  • High-contrast color display with a range of display options
  • Fast series commissioning
  • Simple configuration of an Ethernet-based fieldbus interface
  • Fast access to product information about the current drive system
  • Direct contact with Customer Support via the Siemens Industry Online Support App
  • Simple connection to mobile devices (e.g. smartphones, tablets) via two-dimensional code (data matrix or QR code)

Basic operator panel for direct connection to the drive

for local operation, monitoring, commissioning, diagnostics


The menu-based operation and 2-line display of the BOP-2 Basic Operator Panel facilitate local commissioning of the SINAMICS G120 drive series. Simultaneous display of the parameter and parameter value, as well as parameter filtering, means that commissioning of a drive can be performed easily and, in most cases, without a printed parameter list.


The BOP-2 is available as an additional option for the SINAMICS G120 drives series.

  • Direct local operation of the drive
  • Simple switchover between automatic and manual operation
  • Standard commissioning using the clone function
  • 2-line display for showing up to 2 process values with text
  • Diagnostics with menu prompting with 7-segment display
  • Door mounting kit, can be mounted in the control cabinet door (achievable degree of protection is IP54/UL Type 12)

 SINAMICS G120 wall mount kits allow simple, direct mounting of G120 modular and G120C compact PM240-2 drives. Designed for use with the latest SINAMICS drives, these low-cost kits are easy-to-install and conform to NEMA 1 and UL Type 1 standards.


Available in power ranges from ½ to 200 hp, and for voltages from 230V to 690V, the streamlined, compact design is consistent for all frame sizes and provides for simple interior mounting.

  • Accommodates all SINAMICS G120 / G120C / PM240-2 / PM240P-2 power modules, control units and operator panels
  • Standardized design 
    for optimum space utilization and for efficient side-by-side mounting with minimal clearances
  • Multiple conduit knockout holes 
    for separate power, motor, I/O and network cabling
  • Built-to-last construction
    featuring galvanized steel 3-sided covers, mounting brackets and a rugged plastic window for BOP / IOP access
