●
Data and operations that can be configured
Data
You can specify these types and values of data for conditional expressions.
Operators
Specify the type of arithmetic operation to execute on the data. (In the table below,
indicates the operator’s left-
hand number,
indicates the right-hand number.)
*1 1 if satisfied, 0 if not satisfied.
Item
Description
Value
Set a constant number as data.
The range that can be set differs according to the selected data type.
For details, refer to “Data types” on page 2-1.
Device Address Set a device address for a bit device or a word device that stores the value to be handled as data.

• You cannot select logical operators in the Trigger Condition Settings dialog box.
• You cannot mix bit devices and word devices in a conditional expression when using other than logical
operators.
As a basic rule, conditional expressions are calculated in order from the left, but when multiple arithmetic
operations are combined, they are calculated according to the operator priority.
For [D 10] == [D 11] + [D 12] * 2 + [D 13], the expression is calculated in the following order.
For the operator priority, refer to Chapter 20 “6.5 About the Priority of the Operator” on page 20-62.
