Project transfer
There are two possibilities to transfer your project into the CPU:
•
Transfer via MPI
•
Transfer via MMC when using a MMC programmer
The structure of a MPI network is principally the same than the one of a
1.5MBaud Profibus net. This means that the same rules are valid and for
both networks you use the same components for building.
Per default the MPI net runs with 187kBaud.
Every bus participant identifies itself at the bus with an unique MPI address.
You link up the single participants via bus connectors and the Profibus bus
cable.
A line has to be terminated with its ripple resistor. For this you switch on the
terminating resistor at the first and the last participant of a network or a
segment.
Please take care that those participants with the terminating resistor are
supplied with power during start-up and operation.
•
Connect your PU resp. PC with your CPU via MPI.
If your PU doesn't support MPI, you may use the ADAM "Green Cable" to
establish a point-to-point connection.
The "Green Cable" has the order number ADAM-8950-0KB00 and may only
be used with ADAM CPUs 8xxx.

Configure the MPI-interface of your PC.

you transfer your project into the CPU.
•
If you want to save your project on MMC additionally, plug-in a MMC and
transfer your user application via

During the write process the MC-LED at the CPU is blinking. Due to the
system, the completion of the write operation arrives too soon. It is only
completed when the LED has been extinguished.
