CP340 supports range of protocols.You should know which protocol is supported by the devices connected to the CP (For example 3964R).For each protocol there are settings in HW config and different function you can utilize.

fleur_1984 Posts: 4 Rating: (0)	Thank you, could you please tell what S7 version do you have? Besides, the protocol is used for sensores is not standard, it was created by developers.
