Division 


The result of dividing two integers in an expression will be an integer. If you want a floating point result, multiply the numerator by 1.0 before dividing. For example, POINTA is set to 6 and POINTB is set to 4. The result of the expression POINTA/POINTB is 1, while the result of the expression (POINTA*1.0)/POINTB is 1.5. 

Value of X raised to the power of Y. 

Takes the square root of an expression. 


Format 
SQR expr 
Takes the absolute value of an expression. 


Format 
ABS (expr) Example ABS (2.6) returns 2.6 
Returns the minimum value of two expressions. 


Format 
(expr1) MIN (expr2) Example 3 MIN 4 returns 3 
Returns the maximum value of two expressions. 


Format 
(expr1) MAX (expr2) Example 3 MAX 4 returns 4 
Returns the modulus value of an expression. 


Format 
(expr1) MOD (expr2) Example 9 MOD 8 returns a value of 1 
Rounds a floatingpoint expression to the nearest integer. 


Format 
RND (expr) Example RND (2.6) returns a value of 3 and RND (2.6) returns a value of 3 
Truncates a floatingpoint expression to its integer value. 


Format 
TRUNC (expr) Example TRUNC (2.6) returns a value of 2, and TRUNC (2.6) returns a value of 2 
Rounds a floatingpoint expression to the nearest integer that is smaller than the expression. 


Format 
FLR (expr) Example FLR (2.6) returns a value of 2, and FLR (2.6) returns a value of 3 
Rounds a floatingpoint expression to the nearest integer that is larger than the expression. 


Format 
CEIL (expr) Example CEIL (2.3) returns a value of 3 and CEIL (2.3) returns a value of 2. 
Bitwise Operations
You can use Boolean, integer or floating point number for bitwise operations. If a number/expression is in floating point, it is rounded off to the nearest integer for these operations.
Bitwise operations supported by the Expression Editor are:
Performs 
bitwise AND of two expressions. 


Format 
<expr1> AND <expr2> 
Performs 
bitwise OR of two expressions 


Format 
<expr1> OR <expr2> 
Performs 
bitwise NOT of an expression 


Format 
NOT <expr> 
Performs 
bitwise XOR of two expressions. 


Format 
<expr1> XOR <expr2> 
Performs 
binary left shift on an expression. 


Format 
(expr1) SHL (expr2) Example 2 SHL 1 returns a value of 4. Note: When SHL goes out of range the: Point becomes unavailable. Point Control Pane is starred. Core status log notes that it is unavailable. 
Performs 
a binary right shift on an expression. 


Format 
(expr1) SHR (expr2) Example 2 SHR 1 returns a value of 1 Note: When SHR goes out of range the: Point becomes unavailable. Point Control Pane is starred. Core status log notes that it is unavailable. 
Alarm functions
Alarm functions supported by the Expression Editor are:
Returns 
TRUE if the point is in any Alarm or Warning state. 


Format 
AL(<point id>) 
A1 or WARNING 
Returns 
TRUE if the point is in a Warning High or Warning Low state. 

Format 
A1(<point id>) 
A2 or ALARM 
Returns 
TRUE if the point is in an Alarm High or Alarm Low state. 

Format 
A2(<point id>) 
AH1 or WARNING_HIGH 
Returns 
TRUE if the point is in a Warning High state. 

Format 
AH1(<point id>) 
AH2 or ALARM_HIGH 
Returns 
TRUE if the point is in an Alarm High state. 

Format 
AH2(<point id>) 
AL1 or WARNING_LOW 
Returns 
TRUE if the point is in a Warning Low state. 

Format 
AL1(<point id>) 
AL2 or ALARM_LOW 
Returns 
TRUE if the point is in an Alarm Low state. 

Format 
AL2(<point id>) 
ANA or ALARM_NOT_ACKED 
Returns 
TRUE if the point is in alarm and the alarm has not been acknowledged. Note: The ANA behavior was changed in CIMPLICITY V.6.1. Prior to V.6.1 it behaved as NACK. The global parameter PTEXP_ANA_EQ_NACK_AND_AL is available to revert ANA behavior to preversion 6.. 

Format 
ANA(<point id>) Important: ANA is not supported for Enterprise points. 
Returns 
TRUE if the alarm has not been acknowledged, whether or not the point is in an alarm state. 


Format 
NACK (<point id>) 
Conversion operation
Convert a variable that consists of numbers in text string format to a numeric format that can be included in calculations. 
Logical operators
You can use Boolean, integer or floating point numbers for logical operations. If an expression has a nonzero value, it is TRUE; if the value is zero, it is FALSE.
Performs 
Logical AND of two expressions. 


Format 
<expr1> AND <expr2> 
Performs 
Logical if A is TRUE, then B, else C. 


Format 
If (expr1) THEN (expr2) ELSE (expr3) Or (expr1) ? (expr2) : (expr3) 
Performs 
Logical OR of two expressions. 


Format 
<expr1> OR <expr2> 
Performs 
Logical NOT of an expression. 


Format 
NOT <expr> 
Performs 
Logical XOR of two expressions. 


Format 
<expr1> XOR <expr2> IF (expr1) THEN (expr2) ELSE (expr3) or (expr1) ? (expr2) : (expr3) Performs a logical If A is TRUE, then B, else C.
