A variety of tool types can be called from the machining program. The following definitions are used
in the examples that follow:
N
= Tool for which a pocket number is defined in the tool table. (Normal).
M
= Tool for which no pocket number is defined in the tool table. These tools must be changed
by hand. (Manual).
S
= Special tool (defined in tool table).
Nine different combinations of tool-change sequence are therefore possible. For many tool-change
sequences, for the tool magazine to be controlled, two pocket numbers (tool numbers) must be
output in succession for one TOOL CALL. This is reported to the PLC by markers M2093 and
M2600. The PLC must evaluate and acknowledge both pocket numbers (tool numbers).
The logic diagrams for the nine different tool-change sequences are shown on the following pages
(activated by TOOL CALL).
