Hi Lukas, It took me some time to evaluate that because of the strangeness of the case. In Siemens communications, they do not update "TPDU Number" at the COTP link layer, it is always zero. The TPDU if used incrementally at the S7 layer The Siemens CPs discard this field, which is why the driver works, but in the particular case of the Odot equipment it will take it into account and expect it to always be zero. I tested the driver against the CP 443-1 (S7-400) and everything worked without problems. As indicated, there are other functionalities in the driver that form the message including the COTP layer (diagnosis request, subscription, etc.), which I must evaluate.
