STEP 7 -- Creating S7 programs -- Executing operations

	How in STEP 7 V5.x do you program signal generation (rectangle, sawtooth, triangle, sinus) using the cyclic interrupts?
	How do you determine the velocity, acceleration and distance?
	How can you address I/O bytes and individual bits via the I/O?
	How do you implement numerical differentiation in STEP 7 V5.5?
	How can you convert a hexadecimal number into ASCII characters with STEP 7 V5.5?
	What should you watch out for with the display of negative integer values in the LAD/STL/FBD editor when monitoring?
	Information on the topic of "Executing operations"
	How do you calculate power, exponential, root, polynomial, logarithm and linear values and how do you convert trigonometric functions into degrees?
	How can you convert a number value of the data type INT into a string in S5TIME, or into the data types BCD and REAL?
	How can you delay the output signal in relation to the input signal?
	How can you accumulate physical flow measurements (e.g. mass flow rate, flow velocity) to an overall value?
	How do you monitor a 32-bit field, evaluate the position of an active bit and access individual bits of a double-word?
	How can you link variables and block parameters with each other?
	How do you check real numbers for parity?
	How is numerical integration programmed in S7-SCL and STEP 7?
	When is there a first scan in logic operation sequences?
	What does the NOP statement in the STL editor mean in STEP 7?
	How accurately can I calculate with REAL numbers that are used in extensive formulas?
	Which functions and IEC standard functions exist in STEP 7 for converting and comparing string variables?
	How do you program a shift register with the LAD/FBD statements in STEP 7 V5.5 and in V11?
