Field Device Access Point

What Is It?

The Honeywell OneWireless™ Field Device Access Point (FDAP) is a rugged, industrial-grade meshing access point designed for ISA100™ Wireless (IEC 62734) and WirelessHART (IEC 62591) field instruments. Engineered for deployment in hazardous plant environments (Class 1 Div 1 / Zone 1), the FDAP plays a critical role in establishing a reliable, secure mesh network for wireless instrumentation.

Once deployed, the FDAP automatically discovers and connects to nearby wireless devices—including other FDAPs and ISA100 Wireless and WirelessHART field instrumentsforming a self-healing IEEE 802.15.4 mesh network. It also supports wired HART field devices via wireless adapters, expanding flexibility across a wide range of instrumentation.

Key Features:

• Supports Both ISA100 Wireless and WirelessHART Standards:
  Seamlessly integrates with all compliant field instruments, offering a vendor-agnostic networking solution.
• Antenna Diversity for Enhanced Reliability:
  Dual antenna configuration ensures robust performance in multi-path indoor and outdoor environments.
• Auto-Discovery & Self-Healing Mesh Networking:
  Devices are automatically recognized and integrated into the network, ensuring ease of deployment and reliable operation.
• Hazardous Area Certification:
  Rated for Class 1 Div 1 / Zone 1 environments, making it suitable for mission-critical monitoring and control in extreme industrial settings.
• Low-Latency Data Transmission:
  Supports update rates of under 10 seconds, enabling use for open loop control and other time-sensitive applications.

What Problems Does It Solve?

The FDAP simplifies the deployment of wireless field instruments in complex industrial environments where running wired infrastructure is costly or impractical. It ensures reliable communication in harsh conditions, supports critical monitoring and control, and provides a future-ready platform for expanding digitalization in hazardous operations.
