5.3 Programming the traversing blocks (only in the pos mode, P700 = 2)
The single traversing blocks and programs have the same structure
referred to the parameter structure.
The following is valid for single traversing blocks:
– These blocks must be individually selected and started.
– The program–specific instructions which occur in the traversing
blocks (e.g. path mode) are ignored in the traversing blocks (refer
to Table 5-6).
The following is valid for programs:
– A program is started by selecting and starting a block within the
program. The additional blocks are then automatically executed
as programmed.
Blocks 3 to 27 can be combined to form programs via P99:21 (Program
Manager).
The following rules apply when defining programs:
1. The value, saved under an index of P99:21, is the block number of
the first block in the appropriate program area.
2. The block number of the last block in the program area is obtained
from the start of the block of the next area minus 1.
3. Valid block starts lie in the range between 3 and 27.
4. The last block of the last valid program area is 27.
5. All block numbers from the first block of the first program area are
single blocks.
6. All entries from P99:21 are evaluated in the sequence of the index
until an invalid block start or a value less than the previous value is
found.
The factory default for P99:21 is as follows:
