I find an option in the hardware configuration of the PLC to send a time message to the PC 427B. What have I to configure in the PC 427B to force windows clock synchronization? configuration: PC 427B with CP5611. Windows XP embedded. SCADA is not WinCC. PLC S7-400 with CP 443-1. Note: I have already search in the FAQ and existing forum threads without success. Thanks in advance for help. Nicolas.

The onlyCPs on PC side which support Time synchronization are the Hardnet CPs. For example the CP 5613 or CP 5623. If you insist on the CP 5611... how about this idea. As the function itself is not available on the CP 5611 how about reading the time from one of the PLCs and changing your system time by a little application? Just as an idea. I hope this will solve your problem. Best regards J_Bell

J_Bell Posts: 5822 Rating: (411)	Dear Nicolas, I am sorry. The on board card is a CP 5611... it is just missing the PCI interface on it... because it is directly connected to the backbone bus. If you really want to use the hardware supported time synchronisation you need the CP 5613 / 5614 or CP 5623 / 5624. The Software solution by reading from the PLC ... will take some time... so it is not as precise as the time Sync over the network directly. I hope I am of any help. Best regards J_Bell
