Late synchronization at program end (P-CHAN-00033)

This parameter is used in conjunction with the snchronization types MVS_SLM and MVS_SLP (Late Sync). It controls the reaction on open Late-sync M-functions at program end. This is possible if there was no G01 until program end (for MVS_SLM) or if no explicite synchronization was programmed (for MVS_SLP).

All open Late-sync M-functions at program end are still active at the next program start. This means that all open Late-sync M-functions of the first part program will be triggered firstly by a Late-sync event (G01 or #EXPL SYN) of the second part program.

1

Waiting at program end until all open Late-sync M-functions have been acknowledged by PLC.

EXAMPLE: It should be waited at program end until all open Late-sync M-functions have been acknowledged by PLC.
