Operation of the ET 200iSP IM PROFIBUS variant with older CPUs

Operation of the ET 200iSP with older CPUs
CPUs must support DPV1 mode.
4.15 Time synchronization with a flexible time interval
Description
Time-of-day synchronization ensures that all clocks in a plant have the same time. A master clock
distributes the time in a configurable cycle to all other components in the automation system
that have a clock. The components use this time to set their own clocks.
Time synchronization is the basis for time stamping.
The higher-level component (CPU) of the ET 200iSP bus system must provide the signal for clock
synchronization.
The synchronization interval can be set in the configuration tool in the properties of the interface
module.
The longer the synchronization interval is set, the lower the accuracy of the time stamping.
