4.6.6 Synchronizing individual SIMOLINK rings
NOTE
4-54
When using the FM458-1 DP and the EXM448-2 module, there are
additional ways of synchronizing up to three SIMOLINK masters on a
slave ring that in this case act as clock master. This operating mode is
set-up as follows: For the FM458-1 DP module, the LE bus interrupt of
the leading slave ring (for EXM448-2 is only permitted as the first
interface as master clock) is set as source for the T0 clock cycle - and for
the master interfaces to be synchronized, operating mode 4 or 5 is
selected. In this case, the systems are synchronized almost jitter-free.
When using 2 EXM448-2 connected to an LE bus, only one of the two X1
interfaces of the EXM448-2 can be used as clock master.
The clock cycle of the "clock master" can fail in operation (e.g. if the
leading ring is isolated). This is the reason that measures must be
configured so that when the clock cycle returns, new synchronization to
function block DTS can be initiated.
