MK_SPV_SYMBOLANZAHL
This machine constant defines the size of the symbol table, which is required
for managing symbolic program numbers. If a larger value than 0 is entered
for this MC, symbolic program names can be used when programming the
DIN programs. During this process, dynamic program numbers between
32768 ... 65534 were assigned program names. For further information on
this, refer to chapter "CNC programming".
4.4.5
MK_HEADERANZAHL
This machine constant determines the number of "head entries" for the
management of the DIN programs in the main memory. An entry of this kind
is required in each DIN program in the main memory. Each head entry takes
up 32 byte in the internal main memory (see MK_SPV_SPEICHERGROESSE).
To store a max. of 100 DIN programs in the main memory at the same time,
use a default value of 100.
4.4.6
MK_KANALANZAHL
This machine constant determines the number of NC channels, in which DIN
programs can be executed at the same time.
Value
Meaning
1
Only one channel is provided for the execution of DIN programs (default).
2
Two channels are provided for the simultaneous execution of DIN programs.
)
Note!
For each channel, additional resources of calculating time and
main memory are required. Therefore, only increase this MC if
you really need several NC channels.
Please bear in mind that a program in the second channel cannot
be started via the start key. It can only be started from a program
in the first channel. For further information on multi−channels,
refer to chapter "CNC programming" in the descriptions for G22
