connected properly.
The network settings of the computer do not match the network settings of the
SC-COM.
Corrective measures:

that are connected to the RS485
communication bus.
The data transmission protocol and the baud rate are not configured properly.
Corrective measures:
• Make sure the data transmission protocol and the baud rate for the
connected devices are configured properly.
• Make sure the RS485 cable is connected properly (refer to the RS485
cabling plan at www.SMA.de for information on how the cables should be

Corrective measures:
• Enable data transmission to the Sunny Portal (see Section 7.3.1 "Registering
the SC-COM in Sunny Portal", page 27).
• Make sure the plant name and e-mail address you entered are correct.
You may need to register again in the Sunny Portal.
After an FTP download, the
Internet Explorer shows old
SC-COM data.
The cache behaviour of the Internet Explorer means that an outdated version of
the data is loaded from the SC-COM.
Corrective measures:
• Use an FTP client such as FileZilla to load data from the internal FTP server
of the SC-COM.
The events in the event report do
not appear in the expected
location under "Time".
The time settings of the SC-COM and the connected device do not match.

Synchronise the time settings of the SC-COM and the connected device
(see the manual of the connected device).
