Communication
2.2 PROFINET communication
The following settings are also made:
● NTP server address: Enter the NTP server address when the "Activate NTP
synchronization" checkbox is selected.
Note
Adoption of the NTP server address
The NTP server address is not adopted until the device has been restarted after the
supply voltage has been switched off and on again.
● Cyclic update interval: Time interval in seconds at which synchronization of the time of
day with the NTP server is performed
● Time shift: Time difference in minutes between UTC time (UTC = Universal Time
Coordinated) and the time in the device.
Examples:
● Time shift for CET (Central European Time): +60 min
● Time shift for CST (Central Standard Time, North America): -360 min.
If an NTP server address has not been configured or a server was not found on the network,
you can also set the time of day using SIMOCODE ES. To do this, proceed as follows:
Mark the relevant SIMOCODE device in the project navigation window and then select
"Connect online" to establish a direct connection to the device. Expand the list of device
settings by clicking on the arrow on the left of the SIMOCODE device: You can now select
"Commissioning → Set time (= PC time in UTC)" to download the time of day of your PC to
the SIMOCODE device.
Note
Command execution
Commands are executed immediately.
If a valid time of day is available (either synchronized by NTP or set via SIMOCODE ES), the
entries in the error buffer / error protocol (i.e. log) will be additionally displayed with the time
of day. In addition, the "Clock set (NTP)" and "Clock synchronized (NTP)" messages are
displayed.
Note
Access using OPC UA
A valid time of day is necessary to be able to use the "Sign" and "SignAndEncrypt" OPC-UA
Security Modes.
Simple Network Management Protocol (SNMP)
SNMP is a network protocol for monitoring and controlling network elements (e.g. switches).
SIMOCODE pro V PN (GP) supports the Ethernet service SNMP. MIB-2 (RFC1213) is
supported. R/W objects can be changed with SNMP tools and are stored in the basic unit.
After replacement with a new basic unit from the factory or a basic unit that has undergone a
general reset, the R/W objects will be in the factory settings.
