The target settings for memory layout can be configured in Target Settings dialog's Memory Layout tab in CODESYS.
|
The number of data segments in Project > Options > Build > Number of data segments must be set to 1 less than the maximum number of global data segments is in Target Settings > Memory Layout > Maximum number of global data segments.
Example: Maximum number of global data segments = 5 (Target Settings > Memory Layout > Maximum number of global data segments) Number of data segments= 4 (Project > Options > Build > Number of data segments) |
|
To use CODESYS debug functionality, set the target settings so that PLCopen application is run from RAM. If the application is run from flash, debugging can be done one POU at a time if the POU size is under 4 kBytes (Total size of data memory = 16#1B000).

The default settings for Epec 3606, 3610 and Epec 4602 control unit are as follows:
