Logging on to the web server
You can only use functions for controlling the motor feeder after you have logged on to the
web server with user name and password. Only then are the buttons with a controlling
function active.
The log-on dialog box is only available via a secure https connection.
Certificates:
To enable the web browser to access the web server via an https connection, certificates are
mutually exchanged. On each change of the SIMOCODE pro V PN IP address, a unique
certificate with a validity of two years is created for this purpose.
You can also install a CA certificate with a validity up to 2037 via the integrated web server
as follows: Click the "Download certificate" link in the header of the home page and open or
install the CA certificate.
Note
Installing the SIMOCODE pro CA certificate
You only have to install the SIMOCODE pro CA certificate once for the web client inquestion
and it then applies to all SIMOCODE pro V PN devices.
If you do not install the CA certificate, the web browser will signal a certificate error when the
connection is established to SIMOCODE pro V PN.
Time-of-day synchronization by the NTP procedure
SIMOCODE pro V PN (GP) has a non-battery-backed realtime clock that can be
synchronized via the NTP procedure.
Network Time Protocol (NTP) is the implementation of a TCP/IP protocol for time
synchronization in network. The NTP procedure uses hierarchical time synchronization, that
is, an external clock (e.g. SICLOCK TM or a PC in the network) is used for synchronization.
The device transmits time-of-day queries to the configured NTP server at configured time
intervals. Using the responses of the server, the time of day of the non-battery-backed clock
is synchronized in SIMOCODE pro. This ensures that a synchronized time of day is available
shortly after the supply voltage is switched on.
The NTP synchronization is configured with the SIMOCODE ES configuration software
under "PROFINET Parameters → NTP procedure/synchronization."
