S3 

§4. Concept

S3 DCS project development cycle is split into the several functional levels:

Figure 1. Functional Levels
Figure 1. Functional Levels

  • Level of PACs topology and connectivity editing, including network and OPC topology set ups. PAC could be added from database or from network search.
  • Level of particular PAC configuration , I/O connection, dashboard editing, tags editing

  • Level of HMI/Database editing for superposed levels of ACS. It includes advanced multimedia displays, real time and historical trends, alarms, reports
  • Level of control tasks editing. Control logic implementation based on IEC-61131 languages. Could be downloaded to PAC for I/O control or can be used as script languages for various applications.

  • Level of project documentation generation. All information from upper levels is collected here. Full set of in-line and project documentation for the whole system is created.

Common features

  • Plug-ins technology
  • Can work with third party's ActiveX
  • Tag configuration information is accesible from anywhere, easily and transparently
  • Any changes in tag configuration is reflected immediately where it is used and these changes are initiated certain actions.
  • Bulk tag editing mode.
  • Providing 'on fly' tag creation capability. These tags could be connected to I/O or OPC afterwards if necessary
  • Hot keys, context help, rollbacks
  • Software PAC simulator and remote debugger
