Profibus S7 300 monitoring

It is possible to monitoring the ladder via notebook in an S7 300 ET200U profibus.
If possible, how?

If someone open the program with Step7 and print it out for you in a notebook format maybe

With monitor you probably mean seeing the status of the code while online.
If you have the source program and interface for the laptop to connect to the CPU.
Depending on the CPU, you need an interface for the laptop for MPI, Profibus or Ethernet.
What kind of CPU do you have ?

edit: You seem to indicate that the CPU has Profibus. Maybe you use it to connect the CPU to ET200U modules.
But depending on the CPU you may also be able to connect via MPI or Ethernet.

Another thing, are you sure that the ET200 is ET200U ?
ET200U is obsolete and was S5-100U modules connected via Profibus.
