ISPSoft User Manual Error Log Location If the PLC option button is selected, error logs will be stored in the special data registers in the CPU modules. If the PLC and PLC CARD option button is selected, error logs will be stored not only in the CPU module, but also in the memory card. Twenty error logs at most can be stored in an AH500 series CPU module. If there are more than twenty error logs, the oldest error log will be overwritten by the latest error log. However, if the PLC and PLC CARD option button is selected, and there are more than twenty error logs, the oldest error log will be backed up in the memory card before the oldest error log is overwritten.
