3.4 File and Program Management
Initialization programs
These are programs with which the working memory data is 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
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.
There are:
Identifier
NC
CH<n>
AX<n>
TO
COMPLETE
Create initialization program at an 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 is 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.
Procedure for multi-channel controls (CHANDATA)
CHANDATA(<channel number>) for several channels is only permissible in the file
_N_INITIAL_INI. This is the commissioning file with which all data of the control is initialized.
