Operators
The operators listed below can be used.
Operator Descrpton Example
+ Unary plus operator +ch(00010)
– Unary minus operator –ch(00010)
! Logical negation operator, 1 when 0 and 0 !ch(00010)
when non-zero
+ Addition ch(00010)+ch(00011)
– Subtraction ch(00010)–ch(00011)
* Multiplication ch(00010)*ch(00011)
/ Division ch(00010)/ch(00011)
% Remainder ch(1)%ch(2)<=1 ? AlarmAck() : 0
< Less than, 1 when the condition is met and 0 ch(1) > ch(2) ? AlarmAck() : 0
when it is not
> Greater than, 1 when the condition is met and 0 ch(1) < ch(2) ? AlarmAck() : 0
when it is not
<= Less than or equal to, 1 when the condition is ch(00010)<=1.0 ? StartRec() : 0
met and 0 when it is not
>= Greater than or equal to, 1 when the condition ch(00010)>=1.0 ? StartRec() : 0
is met and 0 when it is not
== Equal to, 1 when the condition is met and 0 ch(00010)==1.0 ? StartRec() : 0
when it is not
!= Not equal to, 1 when the condition is met and 0 ch(00010)!=0 ? StartRec() : 0
when it is not
&& Logical product ch(1) && ch(2)==1 ? AlarmAck() : 0
|| Logical sum ch(1) || ch(2)==1 ? AlarmAck() : 0
^^ Exclusive OR ch(1) ^^ ch(2)==1 ? AlarmAck() : 0
? : Conditional operator ch(00010)>=1.0 ? StartRec() : 0
(Write a ? b : c to mean b if a is met and c if not met)
, Order operator Condition?(ResetTimer(), StartRec() : 0
The order of precedence of the operators is as follows.
+ – ! (unary operators) ← + – * / % (arithmetic operators) ← < > <= >= == != (relational
operators) ← && || ^^ (logical operators) ← ? (conditional operator) ← ,(order operator)
