Derived Alarm and Control Equations

Virtual alarms and control relays can be created from derived formulas using the following operations:
_OR : Set the current operation to OR.
_AN : Set the current operation to AND.
_NO : Set the current operation to NOT
_XR : Set the current operation to XOR.
D : Tag to change the active display number.
C# : Used as a constant where # is either a 1 or a 0.
. : Used like a comma to delimit numbers.
- : Used to specify a range of points.
S : Used like an open parentheses.
F : Used to end or close parentheses (All open parentheses must have a matching close parentheses).
Spaces included here are for readability purposes only.
!
Hot Tip!
· Precedence of the operations are always left to right unless using S and F for parentheses.
· All number references can either be one or two digits.
_OR D1.3-5 is logically equivalent to (1.3 || 1.4 || 1.5)
_AN D 1.3-5 D2.6 _OR D3.7 is logically equivalent to ((1.3 && 1.4 && 1.5 && 2.6) || 3.7)
_OR D01.03-05 D02.06 _AN D02.07 D03.10.-12 is logically equivalent to ((1.3 || 1.4 || 1.5 || 2.6)&& (2.7
&& 3.10 && 3.12))
_AN D1.3-5D2.6_OR.7D3.10.12 is logically equivalent to ((1.3 && 1.4 && 1.5 && 2.6 ) || 2.7 || 3.10 ||
3.12))
_AN D1-2 : Control will parse
_OR S_AND1.1-2FS_AND1.3-4F is logically equivalent to (1.1 && 1.2) || (1.3 && 1.4)
_OR C1 D1.1 is logically equivalent to (1 || 1.1)
