1. IO Link Interface Technology: Know Features
and Capabilities
IO Link's features and capabilities have sparked a lot of interest,
from parameter storing to thorough diagnostics. The IO Link
interface increases sensor or field-level device communication
capabilities via a standardised interface. This objective is relevant
not only for complex installations or operations. It's also beneficial
for simpler applications like those found in many automated
systems.
Data from a non-contact rotary sensor, for example, can go beyond
position readings by identifying a weak signal, allowing bladder
accumulators to be scheduled. It enables engineers to access more
information about a sensor's history and health in an application.
Understanding the IO-Link's Advanced Functions
• Storage of parameters:
IO Link stores parameters. When a replacement device is attached to the system, IO Link downloads the settings needed for
simple installation and programming.
• Device verification:
When a device is replaced, IO Link may verify that the replacement product is the correct one. This is useful when sensors or
hubs look similar but have differing capabilities. Device type, manufacturer, or even a serial number can all be used to verify
a device.
• Tags for specialised applications:
IO Link allows users to read and write a string value to an IO Link device's configured "application-specific tag" object. This
enhances device identification within a system. This is useful in the case of a tool changing application, for example, to allow
identification and verification of accurate tooling.
• Acyclic read/write parameter access:
Because it is a digital communication interface, it can read and write parameters from Fieldbus devices at higher levels. The
Fieldbus controller now has complete control over the IO Link device.
In Conclusion:
IO Link can be used in a broad range of automation applications, and even the most simple implementations can reap benefits.
These advantages grow in proportion to the complexity of the entire automation system and the number of IO Link nodes
added.
