uniVAL pi, the interpreter for the SRCI communication standard

Simple way to integrate Stäubli robots with PLC programming language and software

uniVAL pi is the interface that enables Stäubli robot control from a PLC application. All the important robot functions can be programmed with your preferred PLC programming suite, using PLC function blocks. Integration of robots in complex production lines or machines becomes accessible for PLC programmers, reducing your project cost and development effort.

Pioneer in SRCI (Standard Robot Command Interface)

Stäubli is among the first robot brands operational with SRCI and provide the largest coverage of SRCI features.

Efficient

Time saving up to 30% on programming due to standardized programming language
Reduce troubleshooting time with a more centralized cell design. All data and programs are handled by the PLC and not split between PLC and controller

Easy to use

Greater accessibility to programming when working with different robot brands. No Stäubli specific knowledge required
Seamless integration with your existing PLC software suite

Best of both worlds

No compromise on the performance of Stäubli robots. uniVAL pi benefits from the best speed and accuracy possible.

Compatibility with Siemens SIMATIC ecosystem

uniVAL pi allows Siemens PLC developer to program robot using Siemens TIA Portal. All required robot function blocks are provided by the Simatic Robot Library (provided by Siemens) and communication with the robot is performed using the SRCI standard.

HMI and point teaching can be performed using Stäubli's teach pendant or Siemens' SIMATIC Robot Integrator.

Success story

Application example at customer site

Robot-assisted filling of hyaluronic gel
On an innovative filling and sealing line developed by Zellwag Pharmtech, a Stäubli cleanroom robot is responsible for vial handling. On the control side, the six-axis robot can be easily integrated into the Siemens PLC via the uniVAL plc interface, guaranteeing maximum operating and programming convenience.

We are here for you. All over the world.
