• Read/write parameter PrX
A = value of parameter PrX
• Read/write parameter PrX
B = value that depends on the values of A and PrX
• Read-only parameter
PrX indicates the value of A (can be binary)
• Read/write binary parameter
switch position indicates that bx.y=0
• switch is positioned in respect of the value of binary parameter
bx.y
• If A is less than B, C =1 (true) otherwise C = 0 (false)
• The value of G is the lowest among A B C D E and F
• C = 1 only if A = 1 and B = 1, otherwise C = 0
• C = 1 if A or B is 1, otherwise C = 0
• C = A - B
• values derived from hardware
• values transmitted to hardware
• The value of A is converted into B. For example, if the triangular
symbol is marked A/D then the analog value A is converted into
the digital value B
• Maximum value of A is PrX
