13.25 Timing-synchronization between Part Systems
499
(3) If there is no movement command in the same block as the timing-synchronization command,
when the next block movement starts, timing-synchronization may not be secured between
the part systems. To synchronize the part systems when movement starts after the
timing-synchronization, issue the movement command in the same block as the synchronizing
command.
(4) Timing-synchronizing is done only while the part system to be synchronized is operating
automatically. If this is not possible, the timing-synchronization command will be ignored and
operation will advance to the next block.
(5) The L command is the synchronizing identification No. The same Nos. are synchronized but
when they are omitted, the Nos. are handled as L0.
(6) "SYN" will appear in the operation status section during timing-synchronization. The
timing-synchronization signal will be output to the PLC I/F.
