Hello,

Setup: Idevice

1517 PLC as slave

319 PLC as master

Are there any limitation how many bytes the idevice interface can have?

Hello Ludde;

Have a look at the screenshot below, taken from this Application Example:

Configuration and Application of the Profinet I-device functions

https://support.industry.siemens.com/cs/ww/en/view/109478798

The limitations for data echange for I-devices is 1440 bytes in/1440 bytes out.

Hope this helps,
