Corrective Action
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.
•
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.
•
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«).
