Logger
Manual, and User Output (DO Channels, AO Channels, and PWM
Channels)
Specify an integer starting with 1. The arguments for the ManualDO() and ManualAO()
functions are as follows.
<ManualDONo.>: 1-4
<ManualAONo.>: 1-4
Operators
The operators listed below can be used.
Operator Explanation Example
+ Unary plus operator +ch(00010)
- Unary minus operator -ch(00010)
! Logical NOT operator; 1 when 0, or 0 when not 0. !ch(00010)
+ Addition ch(00010)+ch(00011)
- Subtraction ch(00010)-ch(00011)
* Multiplication ch(00010)*ch(00011)
/ Division ch(00010)/ch(00011)
% Remainder ch(00001)%ch(00002)<=1 ?
AlarmAck() : 0
< Less than, 1 when the condition is met and 0
when it is not
ch(00001) > ch(00002) ?
AlarmAck() : 0
> Greater than, 1 when the condition is met and 0
when it is not
ch(00001) < ch(00002) ?
AlarmAck() : 0
<= Less than or equal to, 1 when the condition is
met and 0 when it is not
ch(00010)<=1.0 ? StartRec() : 0
>= Greater than or equal to, 1 when the condition
is met and 0 when it is not
ch(00010)>=1.0 ? StartRec() : 0
== Equal to, 1 when the condition is met and 0
when it is not
ch(00010)==1.0 ? StartRec() : 0
!= Not equal to, 1 when the condition is met and 0
when it is not
ch(00010)!=0 ? StartRec() : 0
&& Logical product, also calculated after NOT ch(00001) && ch(00002)==1 ?
AlarmAck() : 0
|| Logical sum, also calculated when true ch(00001) || ch(00002)==1 ?
AlarmAck() : 0
^^ Exclusive OR ch(00001) ^^ ch(00002)==1 ?
AlarmAck() : 0
? : Conditional operators ch(00010)>=1.0 ? StartRec() : 0
(“if a then b otherwise c” expressed
as [a?b:c])
, Order operator Condition?(ResetTimer(),
StartRec()) : 0
The order of precedence of the operators is as follows. ← indicates that the left operator
has precedence over the right operator.
+ - ! (unary operators) ← + - * / % (arithmetic operators) ← < > <= >= == != (relational
operators) ← && || ^^ (logical operators) ← ? (conditional operator) ← ,(order operator)
