JC, conditional jump With function block JC.. you can branch off forwards to a
jump label LB within the function block list to skip several
function blocks. You use LB.. (jump label) as the jump
destination. The JC and LB function blocks are used in the
standard circuit diagram.
easySafety allows up to 16 conditional jumps.

Wiring of the function block
You wire the function block in the standard circuit diagram
with its enable coil JC..EN. It can be wired directly to the
device terminals IS1 to IS14 or associated internally.
Example of a conditional jump:

h An LB function block must be entered for each JC function
block. You must use the JC.. and LB.. function blocks in
pairs. The jump label LB01 must thus always be used with
conditional jump function block JC01.
h The description of the LB jump label function block is
provided from page 272.
