ExternalHydAxisLibRef

This class represents a standard hydraulic axis of the Tc2_Hydraulic library (without using an FB_AxisHydraulicBase). This allows standard hydraulic axes and TF8560-based hydraulic axes to communicate with the PlcMcManager in one application.

Syntax:

FUNCTION_BLOCK FB_ExternalHydAxisLibRef
VAR_INPUT
    stAxisRef : AXIS_REF_BkPlcMc;
END_VAR

Inputs

Name	Type	Description
stAxisRef	AXIS_REF_BkPlcMc	Reference to the hydraulic axis.

Properties

Name	Type	Access	Description
NextHydAxis	I_ExternalHydAxisLibRef	Get, Set	Interface to another hydraulic axis.
NextHydAxisChainlength	INT	Get	Length of the chain on hydraulic axes.
UseDatFile	BOOL	Get, Set	A TRUE here signals that the axis loads its parameters with function blocks of the hydraulics library from a file during startup. Notice A TRUE must be set before the first Cyclic call.
