General Information

Library Overview

The library IoLinkHandling provides the functionality to configure the IO-Link master and the IO-Link devices from within the application.

Therefore, dedicated function blocks to read and write device parameters, configure IO-Link master user parameters, and react on events generated by the IO-Link master and devices are implemented.

Characteristics of the Library

The table indicates the characteristics of the library:

Characteristic	Value
Library title	IoLinkHandling
Company	Schneider Electric
Category	Generic
Component	Core Libraries
Default namespace	SE_IoLink
Language model attribute	Qualified-access-only
Forward compatible library	Yes FCL

NOTE: For this library, qualified-access-only is set. The POUs, data structures, enumerations, and constants must be accessed using the namespace of the library. The default namespace of the library is SE_IoLink.

Controller Platforms

The IoLinkHandling library is supported by the following controller platforms:

Modicon M262 Logic/Motion Controllers
PacDrive LMC controllers

General Considerations

NOTE: Schneider Electric adheres to industry best practices in the development and implementation of control systems. This includes a "Defense-in-Depth" approach to secure an Industrial Control System. This approach places the controllers behind one or more firewalls to restrict access to authorized personnel and protocols only.

WARNING
	UNAUTHENTICATED ACCESS AND SUBSEQUENT UNAUTHORIZED MACHINE OPERATION Evaluate whether your environment or your machines are connected to your critical infrastructure and, if so, take appropriate steps in terms of prevention, based on Defense-in-Depth, before connecting the automation system to any network. Limit the number of devices connected to a network to the minimum necessary. Isolate your industrial network from other networks inside your company. Protect any network against unintended access by using firewalls, VPN, or other, proven security measures. Monitor activities within your systems. Prevent subject devices from direct access or direct link by unauthorized parties or unauthenticated actions. Prepare a recovery plan including backup of your system and process information. Failure to follow these instructions can result in death, serious injury, or equipment damage.
