3.1.8 Cross-channel program coordination (INIT, START, WAITM, WAITMC, WAITE,
SETM, CLEARM)
In principle, a channel of the NC can execute the program started in it independently of other
channels in its mode group. If, however, several programs in several channels of the mode
group are involved in machining a workpiece, the program sequences in the various channels
must be coordinated with the following coordination commands.
Requirement
All the channels involved in the program coordination must belong to the same mode group:
MD10010 $MC_ASSIGN_CHAN_TO_MODE_GROUP[<Channel>] = <Mode group number>
Channel name instead of channel number
Instead of the channel numbers, the channel names entered in MD20000
$MC_CHAN_NAME[<Channel index>] can be used as parameters of the predefined
procedures for the program coordination. The use of the channel names in the NC programs
first has to be enabled:
MD10280 $MN_PROG_FUNCTION_MASK, bit 1 = TRUE
