(b) Operation of numerical values
There are two kinds of numerical values: Integer type and Floating-point type.
• Integer type : Represents the bit type, single-precision type, and double-precision type of tag
components.
• Floating-point type : Represents the floating-point type of tag components.
The following table lists operation items and types of the results.
Item
Operation of floating-point type
Addition, subtraction, multiplication of
Integer type
Division of Integer type
(c) Operation between character string type values
1) + operator
Combines character strings.
Example: "ABCDEFG" + "HIJ"
2) Other operators
When both of the operands can be converted to numerical values, the operation is performed using the
numerical values.
Both or either of them cannot be converted to numerical values, the job execution is canceled.
At this time, "Operation error" is displayed in the MES interface Execute Log.
Example:"312" "4"
"31AH"
3) Operation between a character string type value and a numerical type value
Same as the case of the operation between character string type values
(4) Precautions resource data send action
(a) Checking resource data
The settings for collecting the resource data must be matched to the settings for the resource data send
action. When the settings are not matched, an error may occur at the job execution.
When setting for the resource data send action, click the
problem in the resource setting.] is displayed.
When the resource data send action setting differs from the setting for collecting the resource data, the
following error message are displayed.
Resource type
Logging
Advanced user alarm
Advanced system alarm
Operation log
Floating-point type in all cases
In the range from -2147483648 to 2147483647 : Integer type
Exceeding the above range : Floating-point type
Divisible : Integer type
Not divisible : Floating-point type
When zero divide is executed, the job execution is canceled.
At this time, "Zero divide error" is displayed in the MES interface Execute Log.
"ABCDEFGHIJ"
"1248"
"4" Cancellation of job execution
