The SELECT Command [MLP]
The SELECT command is used to control the preselection of tools and heads loaded by an automatic tool or head changer. This command is only valid for machines that require preselection of tooling.
![\textbf{SELECT / TOOL}, \mathit{tool\_id} \; \big[,\mathtt{<\!tool\_information\!>}\,\big]](../../_images/math/cfcb8014e5a219d09e79b9707e147867b55b164a.svg)
![\textbf{SELECT / HEAD}, \mathit{head\_id} \; \big[,\mathtt{<\!head\_information\!>}\,\big]](../../_images/math/202fdfd2ec6ae12694f7583784be6be8fce5840b.svg)
Specify a positive, non-zero, tool_id or head_id of the tool or head to be preselected (i.e., made ready for loading). Specify a value of zero (0) to preselect the dummy tool or dummy head.
Other tool or head options can be specified following the tool_id and head_id parameters. See the TOOLNO command for a complete list of allowable tool and head options. Any such options specified are stored in an internal tooling table and will be used on subsequent load and unload commands. Tool and head options are modal and need only be specified once, ideally on a TOOLNO command.
The SELECT command itself is normally optional. GENER has the capability to scan ahead in the CL file and preselect tools immediately before they are required and/or immediately following the previous LOAD/TOOL command. The ability to automatically preselect tools is controlled in QUEST.
