FAQs

  • How do I connect field devices?

    +
    Use Harmony I/O modules (like A-Loop) that match the signal type (analog/digital) and connect to the controller via a fieldbus
  • What are the power/load considerations?

    +
    Monitor continuous current demand, inrush (short-term peaks like 150ms), and peak (longer-term 5s) demands for proper switchgear function.
  • Can I use new fieldbuses like APL with older Harmony systems?

    +
    Yes, through \"APL device ready\" setups, using Ethernet-APL switches and PROFINET proxies to connect PROFIBUS PA devices until native APL devices are available.
  • How does this improve efficiency?

    +
    By integrating data, reducing manual searches, enabling better process insight, and ensuring compliance with standards, leading to higher uptime and lower TCO.
