NTP service for Siemens S7-1500

[hikaru2001]

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?

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 *.
