FP_HTTP_GET_STATUS_ALL

Get status of all Ethernet units using HTTP transmission

This FP instruction gets the information from all Ethernet units nTransferID0–nTransferID15 and writes the values into the DUT FP_CLIENT_STATUS_ALL_DUT.

Parameters

Output

dutFPClientStatusAll (FP_CLIENT_STATUS_ALL_DUT): Stores the values of the Ethernet status of all Ethernet units

Remarks

This instruction is not available in interrupt programs.
Before you execute the instruction, you need to specify the transfer settings using FP_HTTP_SET_MODE or the setting dialog of the HTTP client.
When an error occurs, check the system variable sys_iEthernetConnectionErrorCode for the error code number.

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

if a transfer setting that has not been configured with FP_HTTP_SET_MODE or in the setting dialog of the HTTP client is specified.
if the instruction is executed in an interrupt program

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

if a transfer setting that has not been configured with FP_HTTP_SET_MODE or in the setting dialog of the HTTP client is specified.
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
		dutFPClientStatusAll: FP_CLIENT_STATUS_ALL_DUT;
		bGetStatusAll: BOOL:=FALSE;
	END_VAR

POU body

If bGetStatusAll is set to TRUE, the instruction is carried out. The status values of all Ethernet units are written into the DUT dutFPClientStatusAll.
