ASCII Instruction Error
Codes
The following error codes indicate why the Error bit (ER) is set in the
control data file.
Table: 0.D
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.
