Hi,

I have two S7-1500 PLC's connected by a S7 connection.

How can I make a time synchronization between these PLC's.

On both PLC's is a HMI panel connected.

Regards,

Pepijn

Hello,

perhaps below you will find a solution:

Time synchronization with the NTP process

Hi,

Thanks, for the information.

How can we do it without an NTP Server.

I want to have one PLC as master and the other PLC's as slaves.

Thanks

Thank you for the information.

You could set one of the HMI's as Time Master. The panels the syncronise the time in both PLC's. 

From Help File:

You configure time synchronization for an integrated connection in the "Devices & Networks" editor.

Requirements

• An HMI connection between an HMI device and a SIMATIC S7 1200 has been configured.

• The HMI device must support the "time synchronization" function.

• The "Devices & Networks" editor is open.

Procedure

1. Click the line of the HMI connection in the "Devices & networks" editor.

2. Select the following in the inspector window under "General > Time synchronization > Settings":

   • None: No time synchronization is used.

   • Master: The HMI device sets the time.

   • Slave: The PLC sets the time.

DEAR Denilson Pegaia :

    I have some issue for the NTP Time synchronization issue , i do enable time sync via NTP and set server 1 address, but it is failed to sync with S7 1500 clock,due to local Singapore PLC technical support very hard get the solution from them ,please recommend what should I do following your instruction,thanks!

Are you trying to set the time in the S7-1500 PLC using NTP, or use the s7-1500 to set the clock of other devices, or both?
