4.20.1 Synchronicity
Characteristics
Reproducible (i.e. same length) reaction times are achieved with the SIMATIC with
an equidistant DP bus cycle and the synchronization of the following free running
single cycles:
• Free running of the user program. The length of the cycle time can vary due to
acyclic program branching.
• Free running, variable DP cycle at the PROFIBUS subnetwork
• Free running cycle at the DP slave backplane bus.
• Free running cycle during the signal processing and conversion in the electronic
modules of the DP slave.
In the case of equidistance the DP cycle runs in phase and with the same length.
In this cycle the processing levels of a CPU (OB 61 to OB 64) and the
synchronous peripheral are synchronized. The I/O data are therefore transferred at
defined and consistent time intervals (clock synchronicity).
