What is difference between profibus dp and profibus pa?
First I think I should point out that Profibus-PA instruments do not use RS-485 (such as is used by Profibus-DP), but a MBP (Manchester Coded, Bus Powered) physical layer, as described in the IEC 61158-2 standard. This is why you need a bus coupler to 'translate' the signals from Profibus-DP to Profibus-PA, and to power the PA bus. The maximum transmission rate of Profibus DP network 12Mbps The maximum transmission rate of Profibus PA network 45.45Kbps You need to power the DP instruments, while PA instruments get its power and exchange data via the same PA cable . You need DP/PA link or DP/PA coupler to link DP network with PA . when you use a coupler connected directly to the DP network , then your DP network transmission rate would be decreased to 45.45.

What is the different between foundation fieldbus and Profibus?
Both Profibus(PA) and FF H1 started off in the same working group and have much in common: the physical medium on which both operates is in accordance to IEC 1152-2 intrinsically saftey. Profibus DP which is used in 90% of profibus applications use either RS-485 or an Optical fibre link. When comparing thir implementation on the data layer in Profibus the input and output blocks are located in the controller itself. The controller(master) fetches the data from the field instruments. However no control blocks are moved into instruments. In FF, the input blocks along with the control block are moved into instruments consequently implementing 'control in the field'. The number of devices per segment/loop also varies in Profibus VS FF H1, with the later having a max of 127 and being limited to 32 due to bottleneck of RS-485 and FF to 31 itself. But practically FF system recommends no more than 12 devices per loop with a cycle time of 0.5s while profibus supports 24 with a delay of 400ms.
What is profibus?
Modbus is a industrial communications protocol designed by Modicon in 1979 widely used in industry, while Profibus is a field bus standard developed by various companies (among these Siemens) in the late 80s. Modbus is the protocol that defines how messages are going to be transferred and Profibus defines the standard (set of protocols) that rule the communication system. As you can see they are not exactly the same. However, both are extensively used in the manufacturing industry these days.
How much an PLC have outputs and inputs maximum?
There are PLC with fixed inputs and outputs. There are modular ones which can be added on with inputs and outputs. So number of input and output of a PLC is actually based on the type of PLC you choose. Different types are available in the market.

What is the basic difference between S7-200 and S7-1200 Siemens PLC?
To answer this question is beyond the scope of this site. Your best bet is to go to the Siemens web site and ask the question there. They have a PDF file that explains it all.
What is the basic difference between s7-200 and s7-300?
S7-200 The S7-200 is referred to as a micro PLC because of its small size. The S7-200 has a brick design which means that the power supply and I/O are on-board. The S7-200 can be used on smaller, stand-alone applications such as elevators, car washes, or mixing machines. It can also be used on more complex industrial applications such as bottling and packaging machines. S7-300 The S7-300 is used in more complex applications that support a greater number of I/O points. S7-300 is modular and expandable. The power supply and I/O consist of separate modules connected to the CPU. It is chosen often by the industries that have future expansion plans.
