FP_ETHERNETIP_GET_STATE_TABLE_RUN_IDLE

Check RUN/IDLE bit for state of cyclic communication

This FP instruction checks the state of the cyclic communication by reading the RUN/IDLE bit of each registered node from the node number table 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

Remarks

Bit corresponding to the node number of FP7 whose connection is registered. When the following two conditions are met, it turns to TRUE, in other conditions, it turns to FALSE.

Communication with the target node (FP7) runs normally.
Communication with all nodes except FP7 runs normally when the target node (FP7) is in “RUN mode”.

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_RunIdleNodeTable: FP_ETHERNETIP_STATE_TABLE_DUT;
	END_VAR

POU body

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