FAQ

What is the function of the IO-Link protocol with this module?

IO-Link is a point-to-point serial communication protocol used to communicate with sensors and actuators. With this module, it allows for easy parameterization, advanced diagnostics (like short-circuits or wire breaks), and reduced wiring complexity compared to traditional parallel wiring.

Can this module be used with non-Siemens IO-Link masters?

Yes, IO-Link is an open standard (IEC 61131-9). This module should be compatible with any IO-Link master that conforms to the standard, regardless of the manufacturer.

How is the analog input scaled and what is its resolution?

The analog input is designed for a 0 to 3VDC signal. It has a resolution of 10 bits, which means it can distinguish 1024 discrete levels within that voltage range, providing a precise measurement for compatible analog devices.
