Monitor a step in the Sequence Detail Control

A monitored equipment sequence step shows several functions:
  • The user-configured step name and the
    Equipment Phase
     name.
  • The step execution state.
  • If the step is a source or target for a transfer of control.
  • If the step has a failure.
  • The step is executing.
  • If the step or associated phase is paused.
L5K_SILC_Step_Runtime_withFailure
Item
Description
1
Failure
Phase failure - generated by the Equipment Phase Failure (PFL) instruction in the
Equipment Phase
 logic.
Internal failure - the sequencing engine has encountered a problem with the
Equipment Sequence
.
2
Step Name
The name of the step as configured during creation of the
Equipment Sequence
.
3
Pause status
The symbol shows that:
  • L5K_SILC_pausesubstate1 A pause of the phase logic is pending.
  • L5K_SILC_pausesubstate2 An auto-pause of the phase logic is pending.
  • L5K_SILC_pausesubstate3 The associated
    Equipment Phase
     is paused.
  • L5K_SILC_pausesubstate4 The associated
    Equipment Phase
     is paused and auto-pause is pending.
4
Equipment Phase Name
Each step is configured to reference one phase. The name of the phase is displayed so you know which equipment phase is executing.
5
Transfer of Control (TOC)
A step that has been configured as the source to transfer ownership to a following target step, without stopping the execution of the phase.
The symbol shows:
  • When the top bar is filled, this step is the beginning of a TOC step pair.
  • When the bottom bar is filled, this step is the end of a TOC step pair.
  • When both top and bottom bars are filled, this step is the end of a TOC step pair and the beginning of another TOC step pair.
When transfer of control is not configured, the symbols are not drawn.
6
Step State
When a step is active, and attached to its phase, the step state mirrors the state of the phase. The set of displayed states are: INACTIVE, NOT CONNECTED (active but not attached), IDLE, RESTARTING, RUNNING, RESETTING, HOLDING, STOPPING, ABORTING, HELD, STOPPED, ABORTED, and COMPLETE.
Tip:
<No phase> steps have no associated phase and only have two displayed states: RUNNING and IDLE.
The step state is also represented by the color of the step.
