An intensive test caused the selection of
- the fully modular industrial routers of the MRX series of INSYS icom,
- the VPN service and the M2M-Premium-SIM cards of the icom Connectivity Suite.
COMUNA-metall has now full WAN access freedom during commissioning since the DSL, LTE and LAN extension cards for the modular routers can be combined as desired.
Another huge benefit is the pre-configuration of WAN chains in the router: connection establishment and the prioritisation of the WAN connections are defined there.
This permits COMUNA-metall to deliver all MRX routers with a standard configuration. The routers decide using
- the WAN chains,
- the installed MRcards and
- the available WAN connections
which of them is used with priority and which as fall back option.
If a customer does not want to provide a redundant WAN connection for regular operation, an LTE pool card will be used for commissioning and removed with the next on-site service - a time-consuming change of the configuration is not necessary.
The comprehensive IT security features of this solution – like different VPN tunnels for the service of COMUNA-metall and the customers for example – clear the way for the ISMS certification as per 27001.
