MECip
Operational Description
SECURE
KNX IP devices intended to communicate with each other via the IP (Secure) Routing
protocol must use the same Multicast Address.
Changing the Multicast Address can only be done under the IP (configuration) tab in
the Backbone´s Properties window. It appears after a click on the blue Topology bar.
When MECip-Sec is used as ETS Current Interface and its IP address is changed by a
configuration download, ETS tries to maintain the connection to the Current Interface
(having the previous IP address). To be more exact, the previous IP Address is still
visible in the IP Tunneling window and ETS shows the Current Interface is not reachable.
MECip-Sec (containing the actualized IP address) now is listed under Discovered
Interfaces and must be selected as new Current Interface.
