The original access password for each account is enclosed in the data logger's delivery. The passwords are unique for each Meteo-40 plus. All passwords can be changed by an Admin user. Admin users can also create, edit and delete other accounts. (see Section 4.2.1, “User Management” in Section 4.2, “System Administration”).

The Meteo-40 plus displays the current established connections
(Connection), e.g. AmmonitConnect via modem or using Ethernet directly in
a LAN. The available connection modes are USB, Ethernet and Modem. If the data logger is
available through the tunnel, it will be shown as AmmonitConnect in the
connections list. If maintenance access is enabled, there will be a superscript plus (⁺)
after AmmonitConnect. The current preferred connection for the Internet
access is written in capital letters.
Additionally, the web interface informs about the remaining time until shut down or
whether CECS is configured to run permanently
(Remaining). In brackets the number of running actions are displayed,
e.g. online access or upload of CSV file.
Figure 3.2, “Meteo-40 plus Status Box with Recording Enabled” shows a Meteo-40 plus with recording on and configuration saved which has a primary modem connection and a secondary ethernet connection (e.g. for SCADA via Modbus TCP). CECS is always on and three actions are running.
Figure 3.3, “Meteo-40 plus Status Box with Recording Disabled” shows a Meteo-40 plus with recording off and configuration unsaved which is connected by USB-B. CECS will remain on for 12 minutes and 34 seconds without further interaction and no actions are running.
The data logger time is also displayed. Color coding is used to indicate the clock accuray. If the data logger time is more than 10 seconds away from the browser time, the time is shown in orange. If it is more than one minute away, it is shown in red with an error icon.
