Abort Process Recipe
Figure 6-29 Abort Process Recipe
The abort command is a powerful instruction that will bring the tube in a safe state. Abort
instruction can be implemented in the process recipe to automatically handle undesired
situation such as pressure failure, gas flow problems and temperature related issued.
Additionally a manual operator command can be accessed at this menu.
If a process recipe is aborted (either automatically or by operator) the process controller
(DPC) will return the process recipe to step “0” immediately. Therefore it is of vital
importance that step “0”has been programmed to create a safe situation.
In the event that step “0” can not be used to create safe conditions (which is common in a
production environment where a minimum of operator handling is required) the use of abort
recipes is obligatory.
Then, any abort command will not have the process recipe to be returned to step “0”
immediately but the activated abort recipe will be performed. When the abort recipe has
reached the END command only then the (aborted) process recipe will be returned to step
“0”.
NOTE
Operator initiated aborts may be used if an operator detects a
dangerous situation in the archive that is not handled automatically.
This includes the erroneous starting of the wrong process recipe.
An abort alarm will be generated with indicated time and abort
condition each time an abort command is issued.
