Special Data Registers for Error Information
Two data registers are assigned to store information on errors.
D8005
D8006
General Error Codes
The general error code is stored to special data register D8005 (general error code).
When monitoring the PLC status using
the PLC Status dialog box using four hexadecimal digits 0 through F. Each digit of the error code indicates a different set
of conditions requiring attention. After the error code is cleared as described on the preceding page, the error code box is
left blank.
For example, the error code may read out "0021." This indicates two conditions requiring attention, "User program sum
check error" from the third chart and "Power failure" from the fourth chart. If the read-out displays "000D," this indicates
three conditions exist from only the fourth chart.
