Complete system
ProfiSignal is a complete software system for data acquisition, analysis, visualisation and automation. The software is very user-friendly and combines professional functionality with easy operation. ProfiSignal provides a clear and logical overview of all measurement systems: whether for single or multi-thousand channel applications. For new users, ProfiSignal is quick to learn. ProfiSignal is modular, scalable and available in three versions: Go, Basic and Klicks. Each version has backward compatibility for operability, data files and application projects.

Measurement Database Included
Measurment hardware configuration takes place with the DataService / Configurator software included in ProfiSignal. The software configures hardware and software interfaces and records data securely and permanently.
The DataService saves measurement data to a database. Any ProfiSignal version on the network can then access these databases and immediately display their data as trends.

  • Confgures hardware
  • Records data to data files
  • Records data to databases
  • Calculation functions
  • Monitoring functions
  • Event Alarms (e-mail, text message, fax)
  • User management and password protection systems
  • Standard software interfaces (OPC, Modbus ...)
  • Customized software interfaces (OCX, .NET ...)
