Serial Communications

For serial communications, ClearSCADA uses channel(s) that have:

• An MPIvia serial adapter Connection Type, in order to communicate with the Simatic S7-300 or S7-400 series of PLCs.
• A PPIvia serial adapter Connection Type, in order to communicate with the Simatic S7-200 series of PLCs.

For information on configuring either of the above Connection Types, see Configure the Connection Properties.
