2.5 Hardware interfaces
2.5.1 Real-time clock
A real-time clock (RTC) is located on the device, which is used to validate the temporal validity when
using certificates. The real-time clock is buffered so that the real-time clock continues to run in the
event of a brief power failure. The buffer time is limited and depends on various parameters (ambient
temperature, duration of use, ...) and can range from a few hours to several days.
During the initial installation and if the power failure lasts longer than the buffer time, the RTCs are set
using a browser via the web server (see corresponding section: Setting the RTC via browser).
Therefore, a problem with the validity of a certificate can indicate that the real-time clock is not set. It
is recommended to use a time server in the network (NTP server), then the device automatically
fetches the current time (see corresponding section: Activating the NTP server).

2.6 Software interfaces
2.6.1 OPC UA
The smartLink HW-DP
protocol and allows OPC UA clients to connect to it.
2.6.1.1
FDI communication server
The FDI communication server supports HART (FCG_TS62769-109-1) profiles.
The OPC UA server of the
"FDI Communication Devices". This specification can be found on the FieldComm Group web page
(www.fieldcommgroup.org) and for download on the OPC Foundation web page (www.opcfoundation.org).
An example of an FDI communication client written in Python is available at:
https://github.com/SoftingIndustrial/FDICommClient.

CAUTION
During operation, the device's surface will be heated up. Avoid direct contact. When
servicing, turn off the power supply and wait until surface has cooled down.
CAUTION
The electronic components of the smartLink HW-DP are sensitive to electrostatic
discharges. Damages due to electrostatic discharge can lead to premature failure of
components or intermittent faults at a later stage. Before installing the smartLink HW-DP,
divert the electrostatic discharge away from your body and the tools used.
Note
Do not open the housing of the smartLink HW-DP. It does not contain any parts that need
to be maintained or repaired. In the event of a fault or defect, remove the device and
return it to the vendor. Opening the device will void the warranty!
