6.3.1

Channel synchronization (program coordination)

General
As an example, double-slide machining operations or real-time processes can only be
carried out if it is possible to synchronize processing in two channels. The channels affected
shall perform certain processing procedures time-matched. To allow time-matched
processing, the relevant channels must be joined to form a synchronization group (mode
group).
The channel synchronization is programmed only via the NC language.
Prerequisite
The affected channels must be assigned to the same mode group.
Program coordination
If several channels are involved in the machining of a workpiece it may be necessary to
synchronize the programs.
There are special statements (commands) for this program coordination. In each case, they
are listed in one block.
