Clocking on PROFIBUS DP
Features
Reproducible response times (i.e. of equal length) are achieved in SIMATIC with
an equidistant DP bus cycle, synchronization of the user program on the DP bus
cycle, and the clocked transfer of I/O data to the I/O modules. The clocked
sections of the user program are processed synchronously to the DP bus cycle by
means of clocked interrupts (OB 61 to OB 64). The I/O data are transferred at
defined and constant (clocked) intervals via the backplane bus of the DP slave to
the I/O modules and switched through synchronously to the terminal.
In other words, clocking results in the synchronization of all the previously cyclic
single cycles from the user program in the CPU to the DP cycle on the PROFIBUS
subnetwork, to the cycle in the DP slave and, finally, to the cycle in the I/O
modules of the DP slaves. The maximum jitter is 10
µ
s
.
