Skipped Function Blocks; Positioning In The Function Block Diagram - Eaton easyE4 series Manual

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:
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 arith-
l
metic function block, that was calculated before a JC..- function block was activ-
ated.
Based on these intermediate states, a function block starts
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,
l
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 pos-
itioning. Connect the JC..EN coil with an appropriate contact for activation.
For greater clarity, position the conditional jump function block
JC.. in the circuit diagram if possible directly in front of the func-
tion block(s) to be skipped.
If the error output is to be evaluated, position the function block in the circuit diagram
again. This time use it as a contact and associate JC..E1 with a suitable Boolean oper-
and.
