Siemens SIMATIC S5 Operating Instructions

Examples for corrections in LAD
Basic rules for the correction of
parallel branches
1. TO an existing , only parallel
branches also with
may be
\
added. If a series contact is to be
added to an existing parallel branch,
then the statement
must
first be converted into
(see example 4, page 25).
This sequence of statements is only
possible with
PC 55-130 A/K.
2. If a contact is to be added to a
parallel branch
whlch was
programmed without
and ,
then before doing so, the beginning
\
@ and termination
\ j of the parallel branch must be
inserted. (see example
3, page 24).
