STARTCOMB
To make it possible to provide the directional information from a protection
function, a STARTCOMB block is used in between the application function and the
Start Matrix function.
The STARTCOMB function has one block input and 14 Boolean inputs that
convert the 14 Boolean inputs into a WORD output STDIR, see Figure 225.
STDIRX =[ b0, b1, b2, b3, b4, b5, b6, b7, b8, b9, b10, b11, b12, b13, b14 ]
b0= START (start)
b1= FW (forward)
b2= REV (reverse)
b3= STL1 (startL1)
b4= FWL1 (forwardL1)
b5= REVL1 (reverseL1)
b6= STL2 (startL2)
b7= FWL2 (forwardL2)
b8= REVL2 (reverseL2)
b9= STL3 (startL3)
b10= FWL3 (forwardL3)
b11= REVL3 (reverseL3)
b12= STN (startN)
b13= FWN (forwardN)
b14= REVN (reverseN)

Protection functions
Some protection functions are provided with start and directional outputs, for
example:
