Block that indirectly loads the Value value in a bit in a global variable address.

Ladder Representation

ISTOREBOOL_block

Block Structure

Variable Type	Name	Data Type	Description
VAR_INPUT	EN	BOOL	Block enabling
	Group#	BYTE	Group where the variable is stored
	Address	DWORD UDINT DINT	Address of the global variable, as its group
	Bit	BYTE USINT SINT	Position of the bit to be modified
	Value	BOOL	New value of the selected bit
VAR_OUTPUT	ENO	BOOL	End of operation

Operation

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

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

ISTOREBOOL_example01

The example above stores the value of VALUE in bit 7 of the address 121 in group 3 (GLOBAL_SYSTEM% C), which represents the disable command of CANopen communication. 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 := 121;

BIT : BYTE := 7;

VALUE : BOOL := 1;

END_VAR

DO1 := FB_ISTOREBOOL(

EN:=DI1,

Group:=3,

Address:=ADDRESS,

Bit:=BIT,

Value:=VALUE);
