In the function block list a jump label must be positioned downstream, i.e.
towards the end of the list when viewed from associated function block
“conditional jump”. If it is placed in front of the associated jump location
(backward jump), the program branches to the end of the function block list
and fault contact JC..E1 of function block “conditional jump” closes. If no
associated jump label is set in the function block list, the program jumps to
the end of the list and fault contact JC..E1 also closes.
Example
A jump is to be made downstream of a table function block when marker
M01 has the state 1.
Figure 151:Example of conditional jump

For subsequently inserting function block JC.. in the function
block list to skip other, existing function blocks, the use of the
