3.2 Working memory
3.2
Function
The working memory contains the current system and user data with which the control
operates (active file system).
Example: Active machine data, tool offset data, zero offsets.
Parameters
Initialization programs
These are programs with which the working memory data are initialized. The following file
types can be used for this:
name_TEA
name_SEA
name_TOA
name_UFR
name_INI
name_GUD
name_RPA
Data areas
The data can be organized in different areas in which they are to apply. For example, a
control can use several channels
(not 810D CCU1, 840D NCU 571) and can usually use several axes. The following exist:
Identifier
NCK
CHn
AXn
TO
COMPLETE
Example: create initialization program on the external PC
The data area identifier and the data type identifier can be used to determine the areas,
which are to be treated as a unit when the data are saved.
_N_AX5_TEA_INI
_N_CH2_UFR_INI
_N_COMPLETE_TEA_INI
When the control is started up initially, a set of data is automatically loaded to ensure proper
operation of the control.
