Skipped function blocks
Function blocks, in the function block diagram change the intensity of their color due
to an active » Conditional Jump « JC...
With a skipped function block:
l
The red in a frame of an active function block turns to pink and
l
The black in the frame of an inactive function block turns to grey.
l
The last internal states and values are frozen, e.g. the calculation result of an
arithmetic function block, that was calculated before a JC..- function block was
activated.
Based on these intermediate states, a function block starts
l
Its recalculation as soon as it is no longer skipped,
l
A bit input can be activated in the circuit diagram and
l
A green dot can also be displayed in the simulation,
however, the function block does not change its internal states and values. It con-
sequently does not also change the state of its outputs.
Positioning in the function block diagram
Drag the conditional jump function block JC.. into the function block diagram and
select in the Properties field window the required function block number between 1
and 32 on the Parameters tab.
The conditional jump function block JC.. is now shown at the end of the function
block diagram.
Position the conditional jump function block JCxx in the function block diagram in
front of the function block(s) to be skipped. To do this, activate the context menu of
the JC.. function block and use the Move Function Block function.
Use of the conditional jump function block also requires the placement of a jump
label (LABEL:xx) function block in the function block diagram.
Association in the circuit diagram
Drag the conditional jump function block JC.. onto a coil field of the circuit diagram
and in the Properties Field window select the function block number already used in
the positioning. Connect the JC..EN coil with an appropriate contact for activation.
