Siemens connection help

Hello, I am trying to connect to the following PLC s7-300. The PLC is in a box that takes 1/2 hour to remove from the line and ideally I need to connect when it is in situ, connected to its sensors.

There is a ProfiBus looking cable connected to the port labelled MPI, this goes to an HMI and a service port which has 3 leads soldered.

Using the attached MPI lead will I be able to connect via the service port?

Can I upload the program albeit with no comments?
