testing connectivity after adding a IPS 4240 to the Mars gives an error: PN-0001:PnLogger message map not initialized. This seems to have an issue with the setup of communication using https, but I can https to the IPS from other stations.
If your sensor is 6.1 then this is a cosmetic issue. 6.1 is not officially supported. Have a look at this thread:
