For the user application in the CPU, we use the OB35. The OB35 is a time
OB, where the call cycle is defined in the CPU properties.
OB 35 (Time-OB)

The call cycle of the OB35 may be defined in the "properties" of your CPU
315-2DP at
prompter alarm . Type for example 100ms.
Now the programming is complete. Transfer your project into the CPU and
execute the program.
•
Connect your PU res. PC with your CPU via MPI.
If your PU doesn't support MPI, you may use the VIPA "Green Cable" to
establish a point-to-point connection.
The "Green Cable" has the order number VIPA 950-0KB00 and may
only be used with VIPA CPUs of the Systems 100V, 200V, 300V and
500V. For the employment, the following settings are required:
- Choose the interface parameterization „PC Adapter (MPI) in your
project engineering tool at Options > Configure PU/PC interface. If
needed, you have to add this first.
- Click on [Properties] and set the wanted COM port and the baud rate
38400 at "Local interface".
•
Configure the MPI-interface of your PC.
•
Via PLC > Load to module 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
PLC > Copy RAM to ROM .
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.
As soon as CPU and DP master are in RUN, the counter values are
transferred via PROFIBUS and monitored at the output module of the DP
slave.
