Types of script error Cause
Processing error
Dividend was divided by 0 for division and residue calculation.
Data types are BCD4(B), BCD8(EB), Float32(F) and value out of range is
specified.
Execution time over error
The execution time for one script exceeded 3,000 milliseconds.
Fixed Interval Script execution time over
Writing count error Data count written to the external device address in one script has exceeded 64.
Indirect device error
During the indirect read of external device address, the value of external device
address was read.
Indirect read or indirect write of external device address is performed with the
Global Script.
Parameter error
Value out of range was specified as argument for LINE function, RECTANGLE
function, or CIRCLE function.
Executed the LINE function, RECTANGLE function, and CIRCLE function in a Cyclic
Script.
Fixed interval execution error
Execution interval is automatically adjusted since the execution of the Fixed
Interval Script has taken more time than half of the execution interval specified
in the Fixed Interval Script.
