Description
A S7 adapter for the direct access
The ACCON-MPI-Adapter allows the connection of a PC to a S7 PLC’s MPI interface via the PC’s serial interface.
Perfect fields of application
- As programming adapter to create and change the PLC program.
- As communication adapter for visualizations
- As communication adapter for accessing the PLC’s data
Varied ranges of application
- Programming S7 PLCs with STEP 7
- Connecting visualizations with S7 PLCs
- Logging S7 data (e.g. with ACCON-S7-EasyLog)
Convincing and varied
The ACCON-MPI-Adapter RS-232 uses the same communication protocol like the PC Adapter. Thus, the ACCON-MPI-Adapter RS-232 can used with any software supporting the PC Adapter.
Instead of the ACCON-MPI-Adapter RS-232, the ACCON-MPI/TS-Adapter can be used. This one offers the advantage that it has a bushing to connect a further device. So, e.g. a panel can easily be connected.
Technical highlights
- Low-cost solution for programming and visualizing
- Serial transmission rate up to 115.2 Kbps
- MPI speed up to 187.5 Kbps
- Voltage supply from the CPU
- External 24 VDC voltage feed possible
