Overview

The PLC library Tc3_IoLink is used for communication with IO-Link devices.

For this purpose, function blocks are available that support the “Common Profile” and “Smart Sensor Profile” and enable parameters to be read and written.

Functions

F_IolGetAdsErrorTxt	Conversion of ADS errors to text form.
F_IolGetChannelStateTxt	Conversion of state channel and port to text.
F_IolGetErrorTxt	Returns the IO-Link error as a string in text form.
F_IolGetIolError	Returns the IO-Link error code as E_IOlError.
F_IolGetIolErrorTxt	Returns the IO-Link error code as a string.
F_IolGetPortError	Outputs the state channel as E_IOlPortError.
F_IolGetPortState	Converts state channel to E_IOlPortState.
F_IolGetProfileIdTxt	Converts E_IOlProfileIdentifier to text format.
F_IolIsBusy	Indicates whether a block is being processed.

Function blocks

FB_IoIRead	Reads IO-Link parameters.
FB_IolWrite	Writes IO-Link parameters.
IOL_IdentificationAndDiagnosis	Identifies and diagnoses an IO-Link device.
IOL_MeasurementDataChannel	Defines process data structure, functions, and representation of measurement sensors.

Object-oriented function blocks

I_IolSlave	Defines the parameters.
FB_IOlSlave	Reads out IO-Link parameters.
FB_IolStdVarSlave	Writes and reads out IO-Link parameters.
FB_IolExtIdentSlave	Inherits from FB_IOlSlave.
