Project transfer
There are 2 possibilities for the transfer of your project into the CPU:
•
Transfer via MPI
•
Transfer via MMC at deployment of a MMC reading device
The structure of a MPI net is in principal same to the one of a 1.5MBaud
Profibus net. This means, the same rules are valid and you use the same
components for assembly.
Per default, the MPI net is running with 187kBaud.
Every bus participant identifies itself at the bus with an unique MPI address.
You connect the single participant by means of bus interface plugs and the
Profibus bus cable.
A conductor has to be terminated with its ripple resistor. Herefore you
activate the terminating resistor at the first and the last participant of a net
or a segment.
Please regard, that the participants with the activated terminating resistors
are always supplied with voltage during start-up and operation.
•
Connect your PU resp. your PC via MPI with the CPU.
If your programming device has no MPI-interface, you may use the
ADAM "Green Cable" to establish a serial point-to-point-connection from
your PC to MPI.
The "Green Cable" has the order no. ADAM-8950-0KB00 and may only
be used with the ADAM CPUs of the Systems 8xxx.
Please regard the notes about the "Green Cable" in chapter 1!
•
Configure the MPI-interface of your PC.
•
With
PLC
>
Load to module
in your projecting tool, you transfer your
project into the CPU.
•
For an additional backup of your project on the MMC, you plug in a MMC
and transfer the user application to the MMC by means of
PLC
>
Copy
RAM to ROM
.
During the writing process the "MC"-LED at the CPU is blinking. Due to
the system, a successful writing operation is signaled to soon. The
writing operation is only finished, when the LED extinguishes.
Note!
Further information to MPI is to find under "Commissioning".
