Steps to create an Equipment Sequence diagram

An Equipment Sequence diagram is a graphical representation of a sequence that coordinates the execution of equipment. Each diagram comprises basic sequence elements such as steps, links, and transitions structured in a specific topology. Each Equipment Sequence has one routine that is configured by adding elements and applying branch structures using buttons available from the Equipment Sequence Element toolbar in the Equipment Sequence Editor.Once the need for an Equipment Sequence has been determined, the tasks listed in the following table should be done to create the Equipment Sequence.

	Task	How
	Identify and create Equipment Phases	Considering the equipment associated with an operational unit of equipment, identify the actions that equipment can perform.
	Identify the manufacturing procedure to be automated	Analyze the manufacturing process and break it into a series of manufacturing actions or steps that are performed serially, conditionally, or simultaneously. Identify the conditions when one manufacturing step should stop and the next be started.
	Configure the Sequence Diagram	Construct the diagram routine to model the manufacturing process. Each step represents one use of an Equipment Phase to perform an action. Code the conditions for starting and stopping actions as transition expressions.
	Configure Sequencing Parameters and Step Tags	Analyze the materials and ingredients used by each manufacturing action. The sequencing input parameters provide data to the Equipment Sequence program. The data provided is available to the Equipment Phase input parameters via step input tags. Analyze the reporting requirements. Generated actual values should be stored into the Equipment Phase output parameters. The value of the Equipment Phase output parameter is copied to its associated step output tag when requested to do so or automatically when the phase becomes STOPPED, ABORTED, or COMPLETE. Sequencing output parameters evaluate their expressions when the sequence becomes STOPPED, ABORTED, or COMPLETE.

An Equipment Sequence diagram is intended to control a specific piece of equipment. All steps within the sequence refer to existing Equipment Phase instances within the same controller.
