tExecutionFB
The parameter tSynchrocheck is used to define the maximum allowed time between
the execute command and the input SYNC_OK to become true. If SYNC_OK=true at
the time the execute command signal is received, the timer "tSynchrocheck" will not
start. The start signal for the synchronizing is obtained if the synchrocheck conditions
are not fulfilled.
