instruction has been executed.
Alternatively, there are more NEXT instructions
than FOR instructions.
■Collateral information
• Common Information:Program error location
• Individual Information:–
■Diagnostic Timing
• When instruction executed
Read the common information of the error using
the peripheral device, check error step
corresponding to its numerical value (program error
location), and correct the problem.
