Ladder and FBD Editors

In the Ladder Diagram (LD) and Function Block Diagram (FBD) editors, programs are presented

graphically. The LD editor can portray everything the FBD can, but in addition the LD

can incorporate Boolean variables in the !orm o! contacts and coils

has a po"er rail that connects all net"orks and to "hich contacts, etc. are connected

"ithin net"orks.

LD symbols include contacts, coils, input variables, output variables, #umps and back"ard #umps. $n

FBD program consists o! blocks, #umps, input variables and output variables.

+onnecting /b#ects

The LD and FBD contain t"o editing modes selection mode (cursor 2 arro") and

interconnector mode (cursor 2 pen). In selection mode, you can select programming symbols, e.g.

contacts, and position or edit them in the programming "indo". In interconnect mode, you can

dra" the lines that connect the programming symbols to each other. The selection mode is the

de!ault mode. 3ou can change to the interconnect mode via

dit 4 Dra" Line, the 5Dra" Line5 command is checked i! active

selected in interconnect mode. Logical elements, input and output variables, #umps and

back"ard #umps can also be positioned in interconnect mode.

not assign an action to a step, the step has a "ait !unction until the subse:uent transition is
