FP_ETHERNETIP_GET_STATE_TABLE_NODE

Find all nodes registered for cyclic communication

This FP instruction reads the node number table to find all nodes that have been registered for cyclic communication and stores the values in the output variable of the type FP_ETHERNETIP_STATE_TABLE_DUT.

Parameters

Output

d_dutStateTable (FP_ETHERNETIP_STATE_TABLE_DUT): Destination to which the data is written

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

if the read area is outside the permissible range
if the instruction is executed in an interrupt program

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

if the read area is outside the permissible range
if the instruction is executed in an interrupt program

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		bEnable: BOOL:=FALSE;
		dutNodes_RegistrationNodeTable: FP_ETHERNETIP_STATE_TABLE_DUT;
	END_VAR

POU body

When the variable bEnable is set to TRUE, the function is executed.
