How do you synchronize the time between an S7-1200 CPU and an HMI operator panel?

  • Entry
  • Associated product(s)
Synchronize the system time of your HMI operator panel with the system time of your S7-1200 CPU by configuring tags and blocks and incorporating the configuration in your HMI operator panel.

Description
The following link provides an application example with extensive information about time synchronization and sample projects that help you when configuring.

Time synchronization between an HMI operator panel and a SIMATIC PLC

The time synchronization between an S7-1200 CPU and a TP1200 Comfort Panel is described as Version 1 in the enclosed PDF document. Unpack the zipped file with the sample projects and libraries for WinCC and STEP 7 (TIA Portal) in a separate directory on your hard disk. The "Project_01" includes the configuration of the time synchronization between a CPU 1212C DC/DC/DC and the Touch Panel TP1200 Comfort. Version 1 is the operator panel TP1200 Comfort parameterized once as master and once as slave.
