Hello,

I have successfully set RevPi core3 as NTP server and my PC can get the time from RevPi. However my S7-1500 can't synchronize the time with RevPi. What's wrong with my configuration?

Hello,
Please, could you post here how you set up your REVPI CORE as NTP SERVER. This will help other User. This is the spirit we want to promote here.
Thank you.

Hello,
you can create Wireshark trace.

Hi,

1. Install NTP server
"sudo apt-get install ntp"
2. Configure NTP server
"sudo nano /etc/ntp.conf"
Important part need to be modified in the file.
"
pool 0.debian.pool.ntp.org iburst #Standard time server from Internet
pool 1.debian.pool.ntp.org iburst
pool 2.debian.pool.ntp.org iburst
pool 3.debian.pool.ntp.org iburst

# If you want to provide time to your local subnet, change the next line.
# (Again, the address is an example only.)
##################################################
broadcast 192.168.20.255 #allowed local time client range, here is 192.168.20.1~192.168.20.254
##################################################
"
3. restart NTP server
"sudo service ntp restart"
4. Test
"ntpq -p"
If you have the similar feedback from the terminal, that means you are successful.
The IP address should be with *.
