Ladder Representation

MW_PlcGetPosition2_G0

Block Structure

Variable Type	Name	Data Type	Description
VAR_INPUT	EN	BOOL	Block enabling
VAR_OUTPUT	ENO	BOOL	Output enabling
	PositionAxis1	DINT	Current position of axis 1
	PositionAxis2	DINT	Current position of axis 2
VAR	MW_PlcGetPosition2_INST_0	MW_PlcGetPosition2	Instance of access to block structure

Operation

When the EN input is TRUE, the block reads the current position of the axes.

NOTE!

The stepper motor control must be enabled on both axes. Look at the user manual and parameter manual.

Example in Ladder

MW_PlcGetPosition2_example01

In the example above, the "read" contact enables the reading of the position of the axes. While "read" is TRUE, the "pos1" and "pos2" variables will be updated with the value of the current position of the axes.

Example in ST

The example below displays instructions for applying the example above in ST language.

VAR

enable : BOOL := 1;

done : BOOL;

pos1 : DINT := 0 ;

pos2 : DINT := 0 ;

END_VAR

done := FB_MW_PlcGetPosition2(

EN:=enable,

PositionAxis1=> pos1,

PositionAxis2=>pos2);
