Method for automatic memory layout (P-EXTV-00012)

P-EXTV-00012	Method for automatic memory layout
Description	As of CNC Build V2.10.1025.00 and higher, the CNC can automatically create the external variables in the memory without gaps. External variables can also be assigned to any memory address by using the parameter var[i].byte_offset P-EXTV-00002 or by selecting a 24-byte are via var[i].index P-EXTV-00038. If the automatic and manual address selection is combined, this parameters defines how the CNC generates the automatic addresses for the variables.
Parameter	auto_memory_mode
Data type	STRING
Data range	START_VE_MEMORY: All variables with automatic determined addresses are set to the start of the external memory area without gaps. LAST_USED_ADDRESS: The external variable with automatic address assignment is always created after the last memory area is occupied by the preceding variables.
Dimension	----
Default value	START_VE_MEMORY
Remarks	This parameter is available as of CNC Builds 2.11.2027.01, V.2.11.2807.18 or V3.1.3052.01 and higher. Older CNC builds always use the START_VE_MEMORY setting.
