Building a safe and secure embedded world


Simple connection of Profibus PA Slave devices to Modbus control systems via internal I/O mapping

  • mbGate PA re-uses power conditioners in technology upgrade projects
  • No PROFIBUS DP Intermediate Segment required
  • Prepared for Integration in Standard Engineering and Plant Asset Management Tools

Key Component for Transition to State-of-the-Art Technology

  • Simple replacement of installed PROFIBUS DP/PA segment couplers
  • Re-use of existing PROFIBUS PA segments without requiring modification

Direct Connectivity to PROFIBUS Segments

  • Acting as Modbus Server and PROFIBUS PA Master
  • Connects up to 4 PROFIBUS PA Segments to Modbus TCP

Configuration, Parameterization and Plant Asset Management Using Standard Industry Tools

  • Supports major Modbus engineering tools such as Schneider Unity Pro or Siemens TIA Portal
  • Included CommDTM allowing use in FDT/DTM frame applications
  • EDD-based device parametrization using Siemens Simatic PDM
