Remote access to machinery via the internet
With its wienet mobile routers and the Wie-Service24 service portal, Wieland Electric offers a complete web-based solution for remote maintenance.
Using the wienet router, plant operators and service technicians can access machinery controllers via secure VPN to change settings and check the status of the device. Technicians can also install software updates remotely via the router. The devices connected to the Ethernet network can be reached via the integrated LAN interface, a USB interface or two additional ports with the option of RS232 or RS422/RS485 M-Bus, an additional Ethernet port or equipped with additional I/Os. Each router has a digital input and a digital output as standard which can be used for SMS notifications and commands.
As telephone and DSL connectivity are not always available, internet access via cellular networks is developing rapidly as a global standard. The latest generation cellular networks can now transfer large amounts of data at much lower costs than ever before. wienet mobile routers support HSPA+ for the fastest transfer rate available for cellular networks. HSPA+ offers similar bandwidth to DSL, with maximum download rates of 14.4 MBit/s and upload rates up to 5.7 MBit/s. If UTMS is not available, the router also supports GPRS or EDGE based connectivity.
The WieService24 remote service portal manages the secure openVPN connections and ensures that only authorized users can access the machine. The data transferred via openVPN is encrypted and cannot be intercepted by third parties. The mobile routers integrated into the machine network register with the portal and establish a secure VPN connection via SMS. Service technicians or other PC clients can connect to the portal automatically via openVPN. Even systems with the same IP addresses can be added to the network thanks to 1:1 NAT.
The portal can be set up quickly and easily. The configurations required for the router and PC are generated automatically and provided for download in the WieService 24 portal. The portable is scalable and available in different versions.
