System Program 27 - Error Routine
This program runs each time a system error or warning occurs. If a fault has occurred, motion and pro-
grams are stopped, the ULTRA Plus or IQ is disabled, and the Error output is set (if defined) before this
program runs. If a warning has occurred, motion and programs are allowed to continue, but the Error
output is set (if defined) before this program runs.
When a program is compiled to save to the ULTRA Plus or IQ as the EROUTINE program, the Com-
piler Options must be set for Program type - “Error Program” and Add Debug Information - cleared
(off). See Part 2 • IQ Master Environment, for a complete description of compiler options.
The default EROUTINE program below uses the PRINTERR function to print the error message to the
Operator Terminal screen.
This program location is useful for applications which may need to automatically reset faults and restart
the application program. Other functions such as using a group of outputs to display the error number,
or use PRINT statements to prompt an operator on the cause of the fault, may be implemented in this
program.
