It is defined with a device symbol "@" followed by address (1 – 32).
Definition of the temporary device
Sample definition
Notes:
• All the values for temporary devices are set to "0" when the execution of the script is started.
• The processing inside the curly brackets "{ }" for the data type designation cannot use temporary devices.
■Comment
A note defined in the script is called a comment. The line with "//" defined at the beginning of a line will become a comment.
"//" is defined with a single-byte. Double-byte characters can be written after "//".
Definition of comment
Sample definition
Notes:
• Describing comments to explain the contents of the script is useful especially when another person works on the scripts or when some time
has passed after editing the scripts.
• Comments are ignored (not executed) when the script is executed, so they can be defined freely without interfering the execution time.
1234
Define the numeric value directly.
-1234
Define the negative number with a "-" (minus) symbol at the beginning.
12.34
Decimal number can be defined for real numbers (float).
Define a "." (period) between the whole numbers and decimal numbers.
0x12AB
Define "0" (zero) and "x" (lower case x) at the beginning of the value.
12ABh
Append "h" at the tail of the value.
[Device symbol and address]
(Space between the device symbol and address is not required.)
[D0100]
@address
(Space between the device symbol "@" and address is not required.)
@2
Temporary device number 2
// Arbitrary note
// Store the initial value to calculation data [D0100] for process A
[D0100] = 1234;
