FP_MEWNET_W2_GET_ERROR_HISTORY

Read MEWNET-W2 system register area for errors

This FP instruction reads the MEWNET-W2 system register area for storing errors that have occurred on the MEWNET-W2 unit in the slot number specified by s_Slot.

Input

s_Slot (ANY16): Slot number of expansion unit

Output

d_dutMewnetW2ErrorHistory: Stores the error history in the FP_MEWNET_W2_ERROR_HISTORY_DUT.

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;
		iSlot: INT:=0;
		dutMewnetW2ErrorHistory: FP_MEWNET_W2_ERROR_HISTORY_DUT;
	END_VAR

LD body

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