Description
Information
Corrective Action
Failure of time synchronization.
Check the following issues:
• Is the correct protocol for time synchronization selected
([Device Para / Time / TimeSync / TimeSync] »TimeSync«)?
• Is the timezone set correctly ([Device Para / Time /
Timezone] »Time Zones«)?
• Open the status page of the used protocol. Check, if the
module works correctly.
• IRIG‑B: Is the correct type (IRIGB-00x) selected ([Device
Para / Time / TimeSync / IRIG-B] »IRIG-B00X«)?
• SNTP: See next entry.
Failure of SNTP time synchronization.
There is no SNTP signal for more than 120 seconds,
the SNTP status changes from “active” to “inactive”
and an entry in the Event Recorder is set.
The SNTP functionality can be checked in the [Operation /
Status Display / TimeSync / SNTP] menu.
If the SNTP status is not “active”, please proceed as follows:
• Check if the wiring is correct (Ethernet-cable connected).
• Check if a valid IP address is set in the device at [Device
Para / TCP/IP / TCP/IP config].
• Check if the IP address of a valid NTP Server is set
([Device Para / Time / TimeSync / SNTP] »IP Byte1«…»IP
Byte4«)?
• Check if SNTP is used for time synchronization at [Device
Para / Time / TimeSync / TimeSync].
• Check if the Ethernet connection is active: [Device Para /
TCP/IP / TCP/IP config] »Link« = “Up”?.
• Check if the SNTP server as well as the protection device
answers to a Ping.
• Check if the SNTP server is up and working.
Failure of the TCP/IP connection
Check the following issues with your local IT:
• Does the device answer a “ping“ request?
• If the device and the PC are part of different subnets, the
gateway and subnet mask have to be set correctly within
the device ([Device Para / TCP/IP / TCP/IP config] »TCP/IP
config«).
• Is network communication blocked by a firewall?
