MODBUS PROTOCOL REQUIRMENTS

I will ask for some from the really large subsections and some of the smaller more obvious main sections. 

MODBUS PROTOCOL STATE DIAGRAMS

Either the server or client diagram could be on the test.

MODBUS RTU REQUESTS AND RESPONSES 

Remember to use the appropriate number of bytes in the message.

When using your calculator only read the rightmost four digits when converting from decimal,
the MODBUS registers are only 16 bits, your calculator will most likely give you
a 32 bit number.   

Use the 0x notation for all the answers.

pyMODBUS FUNCTIONS

Review the pyModbus functions. What they do, what parameters are passed to them, and what data strcture they return.

Try your best to get the proper name of the function.

MODBUS TCP

Review the call flow diagram.  Practice making a call flow diagram that has more then one server transacting with the client.

SQL 

Go and actually practice on W3Schools, the questions will be of the same type as the examples.

There will be two simpler and one more complex question ( INNER JOIN ).

PYTHON 

You will be asked to write functions and small programs to test them.
