mobiLink Interface

Mobile Interface for HART, FOUNDATION fieldbus, Profibus PA


mobiLink is a both Bluetooth and USB solution for commissioning parameterization & maintenance for field devices

  • Single interface for the major Process Automation protocols: HART / Foundation fieldbus / PROFIBUS PA
  • Perfectly suited for handheld host devices due to battery powered Bluetooth operation
  • Compatible with FDT Frame Applications
  • Approved for use in hazardous areas

Multi protocol operation available on mobiLink

  • HART Master, Foundation fieldbus Host and PROFIBUS PA Master  included in one device
  • Temporary attachment to fieldbus segments or HART loops for individual interaction with field devices
  • Fully compliant protocol implementations allow for interference-free access to running plants

Host communication via Bluetooth or USB

  • Built-in batteries and Bluetooth communication enable use of handheld host devices like smart phones and tablets
  • USB interface for bench host operation

mobiLink support of FDT Frame Applications and major Engineering Tools

  • PACTware FDT Frame Application and HART Communication DTM included
  • Communication DTM for Foundation fieldbus and PROFIBUS PA (optional)
  • Foundation fieldbus configuration tool (optional)
  • Application Program Interface for integration into Engineering Systems

Suitable for use in hazardous areas
