FP_MEWNET_F_GET_NUMBER_OF_IO_POINTS

Read MEWNET-F number of I/O points

This FP instruction reads the number of I/O points of the MEWNET-F unit in the slot number specified by s_Slot.

Input

s_Slot (ANY16): Slot number of expansion unit

Output

d_NumberOfPoints (ANY16): Number of I/O points

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;
		iNumberOfPoints: INT:=0;
	END_VAR

LD body

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