Why Engineers Specify This Model
- Deterministic Roaming (iPCF) – Siemens’ proprietary iPCF protocol guarantees handover latency <50 ms, critical for AGV and crane applications where packet loss causes E-stops.
- Dual-Radio Architecture – Simultaneous 2.4 GHz + 5 GHz operation allows backbone uplink on one radio and client access on the other, eliminating throughput halving common in single-radio APs.
- IP65 Die-Cast Aluminum – Fully sealed against dust ingress and water jets; no additional enclosure required for most outdoor or washdown installations.
- Native TIA Portal Integration – Configurable and diagnosable directly from Siemens engineering environment; no separate NMS license required for basic operations.
- Wide DC Input Range – Accepts 24–48 V DC common in control cabinets, eliminating the need for additional AC/DC converters.
- IEC 62443 Cybersecurity Compliance – Meets industrial cybersecurity standards required by modern plant security policies and insurance audits.

Application-Specific FAQ
Q: Can the W786C-2 operate as both an access point and a client simultaneously?
A: Yes. With dual radios, one radio can operate in AP mode serving field devices while the second operates in client/bridge mode connecting to the backbone network — a common architecture in AGV systems.
Q: What is the maximum throughput in an industrial environment?
A: Under 802.11ac on the 5 GHz radio, theoretical throughput reaches 867 Mbps. In real industrial deployments with interference and iPCF overhead, sustained throughput of 150–300 Mbps is typical per radio.
Q: Is this unit compatible with PROFINET over WLAN (PN-WLAN)?
A: Yes. The W786C-2 supports PROFINET over WLAN using iPCF for deterministic communication, meeting the cycle time requirements of most PROFINET RT applications.
Q: Does it require a SINEMA license for basic configuration?
A: No. Basic configuration via Web UI and TIA Portal is license-free. SINEMA Remote Connect requires a separate software subscription for cloud-based remote management.
Q: What antenna should I use for outdoor long-range coverage?
A: For directional point-to-point links, Siemens ANT795-6DN (directional, 14 dBi) is recommended. For omnidirectional cell coverage, ANT795-4MR (5 dBi) is the standard pairing.
Q: Can I use this in a Zone 2 hazardous area?
A: The standard 6GK5786-2HC00-1AA0 is not ATEX-certified. For Zone 2 applications, consult Siemens for the appropriate SCALANCE W variant with Ex certification.
