2.2 Working memory (CHANDATA, COMPLETE, INITIAL)
Function
The working memory contains the current system and user data with which the control is
operated (active file system), e.g.:
• Active machine data
• Tool offset data
• Work offsets
• ...
Initialization programs
These are programs with which the working memory data are initialized. The following file
types can be used for this:
File type
name_TEA
name_SEA
name_TOA
name_UFR
name_INI
name_GUD
name_RPA
You will fine information on all of the file types in the Operator Manual for the operator
interface.
Data areas
The data can be organized in different areas in which they are to apply. For example, a
control can have several channels or, as is commonly the case, several axes at its disposal.
The following exist:
Identifier
NCK
CH<n>
AX<n>
TO
COMPLETE
224
Significance
Machine data
Setting data
Tool offsets
Zero offsets/frames
Initialization files
Global user data

Channel-specific data (<n> specifies the channel name)
Axis-specific data (<n> specifies the number of the machine axis)
