Figure 11-6. Initialization Error Code and its Significance
Locating Parameter Errors in the ISTACK
If the PLC detects a parameter error in DB1 during restart, the PLC remains in the STOP state and
stores the asolute (error) address as well as the relative (error) address in the ISTACK. The STEP
address counter (SAC) in the ISTACK then points either
•
to the address that contains the wrong input or directly
•
in front of the address that contains the wrong input.
The addresses are byte addresses.
