Anybody know?

Example of using itHow is reparameterization performed when replacing the IO link master module or the IO link device?

I have the same question and it's been a while that this thread was started. I looked around and here is a summary for those have the same question but want more information.

IO-Link: a point-to-point data link standard - seems to support smart sensors and replace things like RS232. See:

By the way, this thread is a couple years old and we haven't got any of IO-Link at our site yet.

IODD (I/O Device Description)

Port Configuration Tool

IO-Link - Software

With the Port Configuration Tool (“PCT”), STEP 7 Engineering has powerful software for assigning parameters for Siemens IO-Link master modules and IO-Link devices. S7 PCT is integrated in STEP 7 as of V5.4 SP5 and is called via the hardware configuration of the IO-Link master. Apart from this program form integrated in STEP 7 Engineering, a standalone version of S7 PCT is also available and can be installed separately.

All IO-Link products available to Siemens are already available in the hardware selection catalog of the Engineering. Certified devices from third-party suppliers can be easily and quickly integrated into the Engineering by means of their IODD device description file.

With the Port Configuration Tool, parameter data of the IO-Link devices can be set, changed, copied and saved in the STEP 7 project: In this way, all configuration data and parameters right down to the device level are stored consistently.

The S7 PCT standalone variant allows simple use of the IO-Link with the distributed SIMATIC I/O ET 200 in control systems of other providers (without STEP 7).
