Rules for planning a PCS 7 plant taking strata into account

Please observe the following rules when planning time synchronization, to ensure that the

time deviation of the time master is not too high in relation to the components in the lowest

stratum:

● Use as few strata as possible.

● In most cases using a maximum of four strata is recommended.

● Use the same strata for the same structure elements.

When planning a PCS 7 plant to be synchronized, you should define exactly which hierarchy

would be best for receiving and forwarding the time.
