Instrumentation and control systems architecture is a mission critical task to accomplish the early phases of a new build project. Our experiences range from architecture engineering to detailed systems engineering. TELEPERM XS is our platform for safety I&C applications operating reliably since decades. It comprises all the necessary hardware and software components, including the software tools required for engineering, testing and commissioning, operation and troubleshooting. In addition, we provide cost-effective solutions for stand-alone systems, like e.g. refueling machines, auxiliary systems and lifting devices.
