File and program management
2.2 Working memory (CHANDATA, COMPLETE, INITIAL)
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 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.
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.
