Block that indirectly loads the Value value in a variable.

Ladder Representation

ISTORE_block

Block Structure

Variable Type	Name	Data Type	Description
VAR_INPUT	EN	BOOL	Block enabling
	Group#	BYTE	Group where the variable is stored
	DataType#	BYTE	Data type of the selected variable
	Address	DWORD UDINT DINT	Address of the global variable, as its group
	Value	Depending on the selection of the DataType#	Value to be written in the selected variable
VAR_OUTPUT	ENO	BOOL	End of operation

Operation

When this block has a TRUE value in EN, it loads the Value value in the contents of the Address variable belonging to the Group# group, as the selected DataType#.

When EN has FALSE value, Value remains unchanged.

The ENO value forwards to the next Ladder block the EN value after the operation is completed.

Example in Ladder

ISTORE_example01

The example above stores the VALUE value in WORD format in address 444 of group 3 (GLOBAL_SYSTEM% C), which represents the index of the communication port Modbus TCP. The block ends with success and ENO output is activated.

Example in ST

The example below displays the instructions for applying the example above in the ST language.

VAR

ADDRESS : DINT := 444;

VALUE : WORD := 503;

END_VAR

DO1 := FB_ISTORE(

EN:=DI1,

Group:=3,

DataType:=4,

Address:=ADDRESS,

Value:=VALUE);
