You can manipulate portions of the SFC by starting, stopping, or resetting individual levels of an SFC algorithm. For example, consider an SFC that uses a linked composite containing an SFC for draining the contents from a vessel. If there is an equipment failure that requires you to drain the vessel manually, you could drill down into the composite and click Stop Sequence to stop the SFC from trying to drain the vessel. The title for the SFC is displayed as
Sequenced Stopped
If you want to restart the draining, click Start Sequence.
