The Rapid Roaming (RR) Ethernet Client Modules of the SCALANCE W740 Product Line offer the same features and functionalities as the W746-1 or W746-1PRO-Versions. In addition to that, these devices are equipped with the IPCF features.
The iPCF mode is recommended for applications with a requirement for real-time and predictable response times (deterministic response), even during roaming of moving stations from one access point to the next. This ensures that wireless PROFINET IO is supported and that safety-related signals, e.g. emergency stop, can be integrated into the wireless link. This means that even video signals from moving stations can be transmitted with a high level of quality.
The iPCF mechanism expands the IEEE 802.11 standard and must be available on both the station and the access point (e.g. SCALANCE W788-1RR). In a wireless field in which iPCF is used, no IEEE 802.11-compliant stations can be operated. iPCF is recommended for applications where wireless network nodes move along predefined paths (e.g. suspended monorail).
