# Late synchronisation at program end (P-CHAN-00033)

P-CHAN-00033 | Default setting for 'Late synchronization at program end' at program start
Description | This parameter is used in conjunction with synchronisation types MVS_SLM and MVS_SLP (Late Sync). It defines the reaction to open Late Sync M functions at program end. This may occur if there is no G01 block in the NC program until program end (with MVS_SLM) or if no explicit synchronisation was programmed (with MVS_SLP).
Parameter | prog_start.late_sync_ready
Data type | BOOLEAN
Data range | 0: Open Late Sync M functions at the end of the program are still active the next time the program is started. This means that one or several Late Sync M functions of the first NC program are only triggered by a Late Sync event (G01 block or #EXPL SYN) of the second NC program.

1: At program end, the program waits until all open Late Sync M functions are acknowledged by the PLC.

Dimension | ----
Default value | 0
Remarks | Parameterisation example: At program end, the program waits until all open Late Sync M functions are acknowledged by the PLC. prog_start.late_sync_ready 1
