3.2. System software design<br />

The software used <strong>in</strong> this STG are based on SoCollaborative, which is a part of<br />

<strong>PlantStruxure</strong>.<br />

Three SoCollaborative software components are needed <strong>in</strong> the design of the <strong>time</strong><br />

<strong>stamp<strong>in</strong>g</strong> function:<br />

• Vijeo Citect<br />

• OFC Factory Server<br />

• Unity Pro<br />

In the Process Operator’s Station:<br />

Vijeo Citect Run Time is used to display the <strong>time</strong> <strong>stamp<strong>in</strong>g</strong> value.<br />

OPC Factory Server is used to connect to the PAC system.<br />
