“Security settings for Ethernet SDBs“ box
●
The option is only effective when the system data blocks are stored on the CPU, refer to
the parameter group “Replace module without PG“ (“Save configuration data on the
CPU:“ enabled).
Enabling the option “Check SDB source“ has the following effects:
– When the SDBs are stored on the CPU, the TIM checks the origin of new SDBs. If
SDBs are to be loaded on the TIM from a PG, the TIM rejects loading of the SDBs.
The deleting of SDBs from a PG is also blocked.
– Resetting the TIM from a PG is blocked.
– Updating the firmware of the TIM is blocked.
Here, you make the settings for a TIM 4R-IE DNP3 in a master station for time-of-day
synchronization by up to two NTP servers.
In NTP mode, UTC (Universal Time Coordinated) is transmitted. This corresponds to GMT
(Greenwich Mean Time).
