Examples of editable OS standard displays (faceplates) from the<br />

<strong>PCS</strong> 7 library<br />

I&C libraries<br />

Preconfigured and tested blocks, faceplates and symbols are<br />

organized in I&C libraries and form the basic elements for the<br />

graphic configuration of automation solutions. The use of<br />

these library elements plays a major role in minimizing the<br />

engineering input and project costs.<br />

The comprehensive range of blocks comprises:<br />

■ Simple logic and driver blocks<br />

■ Technological blocks with integral operation and signaling<br />

functions such as PID <strong>control</strong>lers, motors or valves<br />

■ Blocks for integration of PROFIBUS field devices in line with<br />

the PROFIBUS PA profile 3.0 (including standardized evaluation<br />

of the <strong>process</strong> value status).<br />

Continuous function chart<br />

Continuous function chart (CFC)<br />

The CFC editor is the tool for graphical configuration and<br />

commissioning of continuous automation functions. Preengineered<br />

function blocks can be positioned, configured<br />

and interconnected within CFCs with the support of powerful<br />

autorouting and integral configuration of HMI messages. Special<br />

configuration techniques such as chart-in-chart for implementing<br />

hierarchical plans or the multiple usage of chart<br />

block types (chart compiled as block type) or SFC types (standardized<br />

sequential <strong>control</strong>s) in the form of instances offer an<br />

additional rationalization potential.<br />

When creating a new CFC, a new runtime group with the same<br />

name as the chart is created. All the blocks that are subsequently<br />

entered in the chart are automatically added to this<br />

runtime group. Each block is therefore already assigned runtime<br />

properties when inserting, and configuration engineers<br />

can optimize these properties by means of modifications in<br />

the runtime editor or by using algorithms.<br />

The algorithm first determines the optimum block sequence<br />

separately for each runtime group, and then the optimum sequence<br />

of runtime groups.<br />

In addition to convenient editing functions, the scope of<br />

CFC functions also includes powerful test and commissioning<br />

functions as well as individually configurable documentation<br />

functions.<br />
