Transition display states
Transition display states show how the transition execution relates to the overall
Equipment Sequence
execution.Transition Display State | Transition Color | Description |
IDLE | GRAY | The transition is not actively executing. |
ARMED | GREEN | The transition is actively evaluating its expression. |
FIRING | GREEN | The transition expression has evaluated TRUE. The previous steps is STOPPED and the next steps is started. |
STOPPED | BLUE | The transition has completed processing a STOP command and has stopped the transition's execution. |
ABORTED | PURPLE | A Equipment Sequence transition in the ABORTED state has been disabled by an ABORT command and will not advance an Equipment Sequence chart. |
HELD | YELLOW/BROWN | An Equipment Sequence transition in the HELD state has been halted by a HOLD command or HELD because of an Equipment Sequence failure and will not initiate or advance the Equipment Sequence transition firing process until issued a RESTART command. If the transition has been HELD due to an Equipment Sequence failure, the failure should be cleared before issuing a RESTART command. |
HOLDING | YELLOW/BROWN | An Equipment Sequence transition in the HOLDING state is advancing the Equipment Sequence transition firing process. This transitional state is only visible until the scan processing the HOLD command has finished. |
