InputCoE_Polling

This class implements a virtual input for an asynchronous CoE value from an EtherCAT device that is read via ADS. This function can be used for cyclic reading of internal terminal information (such as the internal temperature).

Syntax:

FUNCTION_BLOCK FB_InputCoE_Polling EXTENDS FB_IoBase

Properties

Name	Type	Access	Description
InputScale	DINT	Get, Set	Reserved (compatibility with `I_InputBase`)

Config	I_CoEParameter	Get	Information on the parameter to be read: address, data type, memory type, validation
Device	I_IoEcAds	Get, Set	The ADS address information is used from the device transferred here.
PollingInterval	LREAL	Get, Set	Time interval at which the asynchronous value is updated.
