InputBase

This class is the basis for I/O input elements.

	Class is Abstract Since the class is defined as `ABSTRACT`, the class cannot be instantiated and must be implemented using inheritance.

Variants already implemented:

Name	Description
InputAnalog16	Input module for (up to) 16-bit analog input terminals.
InputAnalog16Status	Expanded input module for (up to) 16-bit analog input terminals with additional status information.
InputAnalog32	Input module for (up to) 32-bit analog input terminals.
InputCoE406	Input module for DS406-based encoder systems via EtherCAT.
InputCoE_Polling	Input element for values from an EtherCAT participant that can be read asynchronously via CoE.
InputDigital	Input element for a digital (Boolean) input signal.
InputDigitalCam	Input element for digital feedback from a hydraulic axis.
InputSsi	Input module for SSI-based encoder systems.

FUNCTION_BLOCK ABSTRACT FB_InputBase EXTENDS FB_IoEcAds

Name	Type	Direction	Description
WcState	BIT	Input	Working Counter State
AdsAddr	AMSADDR	Input	ADS address of the I/O element for asynchronous communication.
Toggle	BIT	Input	Cyclic switching bit that is synchronized with the update rate of the mapping. As a rule, the InputToggle of the WcState structure is mapped for this purpose.
InfoDataState	UINT	Input	Numerical information on the state of the EtherCAT slave (see State).

Name	Type	Access	Description
InputScale	DINT	Get, Set	Scale for scaling the input value.

Name	Description
Cyclic()	Cycle method
GetChannelState()	Reads the status word of the input element.
SetChannelState()	Writes the status word of the input element.
GetProcessIoStatus()	Reads the EtherCAT status of the input/output element.
SetProcessIoStatus()	Writes the EtherCAT status of the input/output element.
GetProcessValue()	Reads the terminal-specific input/output value.
SetProcessValue()	Writes the terminal-specific input/output value.

Type	Description
I_IoBase	Standard interface on FB_IoBase.
I_InputBase	Standard interface on FB_InputBase.
I_IoEcAds	Standard interface on FB_IoEcAds.
I_IoEc	Standard interface on FB_IoEc.

Development environment	Target platform	PLC libraries to include
TwinCAT v3.1.4024.55	PC or CX (x64, x86)	Tc3_PlasticFunctions (>= v3.12.5.0)
