Technical What diagnostic software?
I use and recommend Multiecuscan (MES), www.multiecuscan.net. You don't say what OBD lead you have. There are two basic types of interest to FIAT owners. KL (or VAG-COM and ELM 327. The one you need for your Ducato depends on which modules you want to talk to. For the engine either will work and you can use the free version of MES. For other modules you will need a KL type OBD interface, adaptor lead(s) and the registered version of MES (€50, a bargain). You can check requirements here http://www.multiecuscan.com/SupportedVehiclesList.aspx Scroll down to your model. If a function is in red type you need the registered version.
MES does far more than hand held readers or generic software like Torque.
Download the freeversion of MES and have a play.

My favorite is OBD Car Doctor Pro.
Costs almost nothing and gives excellent details of engine performance in both graphs and listings. Communicates better and faster with the bluetooth ELM327 than Torque.

Problem with this and Torque is that they are only "dashboards" and basic fault code readers. MES gives specific informaton, not just a code number. It also allows advanced diagnostics and service actions like DPF oil degredation reset and Proxi Aliginment. Basic is free, full €50.

244 (02-06) IS OBD (Analogue) - 250 onwards (07 -) is Canbus (Digital)
We tend to use the terms OBD/EOBD/OBDII generically without thinking about what they mean. The primary purpose of the standards is to allow a test station to ensure a vehicles emission system has no faults at it's annual (or whatever) test.
The manufacturers expanded on this to include diagnostic and service facilities. They are a computer communications port and all are digital (apart from the supply voltage). Like most computer communications the standard is built up of "layers". While they can split further Three layers are typical, Hardware, Communication and Data. Hardware includes the connector(s), voltage levels etc. Communication includes the format, number of bit's parity etc. Data is what the "numbers" transferred mean.
The OBD protocols include a number of hardware protocols. We are interested in two KL and CAN. CAN is newer and generally more capable. These are standard. The Communications have a number of standards under OBD, but there are a number of manufacturer variations for additional functionality, especially for KL. The 16 pin socket may carry multiple interfaces. This is why switching or adaptor leadfs are required. Again Data has OBD standards that must be provided, but manufacturers add many more. The Ducato connectivity is mostly KL, but the Bosch ECU on the 2.8 diesel has CAN. and meets the basic requirements.

Depends on the engine fitted. On the 244 version the 2.8 diesel is supported by MES and probably other readers / software to a greater or lesser extent. The BiPower / GPower engine is not supported.
