Figure 176: 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.
The parameter tSynchronizing is used to define the maximum allowed time
between the start signal for synchronizing and the confirmation that synchronizing
is in progress.
