Identifier	Value range	Default	Meaning
number_used_variables (Old syntax up to V2.11.2034.0: anzahl_belegt)	[0; MAX_UNS16]	0	Assuming gapless assignment in var[i].* enter the index of the last variable defined +1 here (i_last+1). Assuming assignment with gaps in var[i].* enter the highest index of the defined variable + 1 here (i_max+1).
var[i].*	i:= [0; 214]		Data records to define variables.
name	ASCII string		See P-EXTV-00001
index	[0; MAX_SGN32]	-1	The index defines the location in the memory where the variable is saved. The entire memory is structured as an array of units of 24 bytes each. An index of –1 indicates that the entry is not used.
type	[BOOLEAN, SGN08, UNS08, SGN16, UNS16, SGN32; UNS32, REAL64, STRING]	UNS32	See P-EXTV-00003
scope	[GLOBAL; CHANNEL]	CHANNEL	See P-EXTV-00004
synchronisation	[TRUE, FALSE]	TRUE	See P-EXTV-00005
access_rights	[READ_WRITE, READ_ONLY, WRITE_ONLY]	READ_WRITE	See P-EXTV-00006
array_size	[0; MAX_UNS16]	0	If an external variable is required not only once but as an array of this variable, the number of elements must be defined. If the variable is not an array, then specify 0.
size	[0; MAX_UNS32]	4	See P-EXTV-00008
create_hmi_interface	[TRUE, FALSE]	FALSE	See P-EXTV-00009
