SEARCHoverIP

Tutorial: SEARCHoverIP

With the SEARCHoverIP function, you can also find your PLC via remote maintenance in the network. For example, "virgin" SIEMENS controllers can be found and configured remotely in the network. Furthermore the search function for controls of the brands SchneiderElectric, Rockwell, Beckhoff and Pilz is supported.

The control systems on the market and their configuration software work mostly with the Broadcast/Multicast/Discover principle during the initial start-up. This principle is based on Layer2 network communication.
I.e. the corresponding configuration software searches via network functions the controls in the network.
In local networks, this is usually not a problem - but in remote maintenance the network is routed (the local area network does not correspond to the remote network area), and therefore, only communication via Layer3 is available. That means that this comfortable way is mostly not available during the remote maintenance and therefore the user has to know the IP-participants and has to specify them manually.

The SEARCHoverIP function offers the reliable and convenient option of performing these search functions via remote maintenance.


Warning

When the SEARCHoverIP function is activated or executed, the "remote maintenance network" (Remote Client) is connected one to one to the LAN network on the device (router) via Layer2.
- Under certain circumstances, this can lead to IP address conflicts.
- Network disturbances on the remote maintenance side (Remote Client) or router LAN side can occur.
The execution of broadcasts and multicasts on the remote maintenance side (Remote Client) causes an additional increased data traffic through the VPN tunnel.


Notice

Always use the SEARCHoverIP function wisely and as an ultimate ratio.
Activate the function only for the duration of the action to find and configure a controller in order to minimize the above-mentioned risks and to reduce the data traffic in the VPN tunnel.
After completing the work, deactivate the function again in the LAN settings of the router.

Please also note that the SearchoverIP function must be enabled in mbDIALUP:
