6F2T0207 (0.01)GRE200 (5,6)- 585 -(ii) Nodes and formulae for interlock-checkFigure 4.4-4 illustrates that an interlock-check is realized by using a number of nodes. Foreach node, the user is required to configure input signals, interlock-operators, and linksbetween nodes. Following that, an interlock-check can be run.Node #7OR(+)Node #1AND(• )Node #3Node #5Node #2Node #4Node #6OutputSignal monitoring pointUsers can see signals at signal monitoringpoints using the GR -TIE MS.Users can seesignals by IEDscreens.OR(+)AND(• ) AND(• )AND(• )OR(+)Input AInput BInput CInput DInput EInput FInput GInput HInput IInput JFigure 4.4-4 Operation of interlock-checkWe can see that equation (4.4-10) is a representation of Figure 4.4-4. This equation is computedin accordance with the priority order of the interlock-operators: the first is parentheses [()], thesecond is AND [•], followed by OR [+].Output = ((A+B) •C) + (D+E•F) + (G•(H+I) •J) (4.4-10)
