ASCII Instruction Error
Codes
The following error codes indicate why the Error bit (ER) is set in the
control data file.
Valid in-line direction:
Input: Flow rate is currently [N7:0] liters per minute and contains [L8:0] particles per liter
contaminants.
Output: Flow rate is currently 25 liters per minute and contains 508000 particles per liter
contaminants.
Input: Current position is [N7:1] at a speed of [L9:1] RPM.
Output: Current position is -37 at a speed of 5 RPM.
Invalid in-line indirection:
Input: Current position is [N5:1] at a speed of [L9:1] RPM.
Output: Current position is [N5:1] at a speed of 5 RPM.
TIP
Truncation occurs in the output string if the indirection
causes the output to exceed 82 characters. The
appended characters are always applied to the output.
Error Code Description Recommended Action
