Operation of the function block
If the JC..EN enable coil is active, the program jumps
forwards over one or several function blocks. The next
function block to be processed is the first to follow the LB
jump label in the function block diagram. If the JC..EN
enable coil is not active, the program is processing the next
function block that is added in the function block diagram
behind JC...
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.
This also skips the last rung 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.
