Hello,

I tried to implement the XBUS_IP_SLAVE protocol and have always a time out with the code 40.
According to the documentation it is the following error:
Frame size not a multiple of 16. Only for WordBit frame type.

My frame is a standard WORD frame.

Any idea?

Nico
Version: 11.2 and 12.0

My configuration in screenshot

4237=634 Slave
4237=630 Slave 02
4237=631 Slave 03
4237=632 Slave 04

Hi Nico,

Another reason for code 40 is the PLC slave memory state is not initialized.

4238=635 MbIpSlaveNotInit
