Siemens 6GK5907-4PA00 SCALANCE W KEY-PLUG W740 iFeatures Client Mode Networking Accessory

The Siemens 6GK5907-4PA00 KEY-PLUG W740 is a removable data storage medium that activates iPCF, iPCF MC and iPRP client-mode iFeatures on SCALANCE W780/W770 and W740/W730 access points operating as clients. It also stores configuration and application data, so replacing a faulty device is a plug swap rather than a reconfiguration, and it holds 256 MiB of storage in a 24.3 x 17 x 8.1 mm module.

Selection Notes

Choose the W740 KEY-PLUG specifically for client-side iFeatures; it targets SCALANCE W devices operating in client mode (iPCF client, iPCF MC client, iPRP client) rather than access-point mode, so it is the module to stock for the moving or subordinate end of a wireless link, not the infrastructure side. The -40 to +75 degC operating rating covers unheated cabinets and vehicle-mounted enclosures, so the module can stay plugged in rather than being pulled out between configuration sessions.
