18-2 USER’S MANUAL
General Error Codes
When reading error data using FUN20, the error code is displayed using one, two, or three digits in hexadecimal notation
(0 through F). Each digit of the error code indicates a different set of conditions requiring attention. If there are none of the
conditions from the first chart (digit on the left), then this digit does not display on the program loader. If there are none
from the first and second charts, then these two digits are not displayed.
For example, the error code may read out “21.” This indicates two conditions requiring attention, “User program sum
check error” from the second chart and “Power failure” from the third chart. If the read-out displays “D,” this indicates
three conditions exist from only the chart on the right.
When control data register D92 is enabled using FUN10, general error code is stored in D92. See page 5-8.

base unit drops below the rated value, the ERR1 indicator is lit. While the power voltage
remains below the rated value, the ERR1 indicator does not go on.
*2: When a program sum check error occurs, operation is stopped momentarily for recompiling the user program. After completing the
recompilation, operation resumes.
*3: Outputs where error occurs are turned off.
