Bit 5 Magazine is a fictitious magazine
"1" signal: The magazine is a fictitious magazine, i.e. the tools are not assigned geometrical
values.
A fictitious magazine is required, for example, for cartridge handling
(loading/unloading list, assignment list). The magazine table is only set up as far as
the last parameterized user block.
If a magazine is a fictitious magazine, bit 4 "with configuring" must be set.
"0" signal: The magazine is a normal magazine.
Bit 4 Magazine with configured locations
"1" signal: The magazine locations are preset with a fixed tool size (no fixed tool coding; free
tool coding is possible for magazine locations for the same tool size).
"0" signal: No fixed tool sizes are assigned to the magazine locations.
Bit 3 Magazine is linear magazine
"1" signal: For a linear magazine (e.g. chain, rotary-plate, etc.).
"0" signal: For a non-linear magazine (e.g. cartridge).
Bit 2 Symmetrical tool search
"1" signal: A magazine will be searched symmetrically by the tool selection of the basic
functions if this bit is set. The search starts from the actual magazine position.
(channel DB, DW 76).
Application: e.g. chain magazine.
"0" signal: The search direction is forwards. The search starts from magazine location 1.
