Kepware's Siemens S7 MPI Driver supports the Siemens C7 PLC, which combines an S7-300 CPU with an Operator Panel and on-board I/O. The Siemens S7 MPI Driver works with this embedded S7-300 just as it would a standalone S7-300.

Note: Users must ensure both that the Operator Panel and the Siemens S7 MPI Driver are configured to support multiple masters and that each has been assigned a unique Master MPI ID.
