11.1.4 Using -VERZW Branching Marker
Symbol CL200 CL400/CL500
-VERZW M188 M242
Using the -VERZW branching marker, step numbers defining the subse-
quent program progress are transferred to the cascade data module. This
facilitates the implementation of simple OR links.
Example:
Ri
g
ht or Left or U
p
or Down
S 3 Branching step
S 4 Left S 6 Right S 7 Up S 8 Dn
S5
