Execution Control Instructions

JUMP and LABEL
• You cannot jump upward in the networks.
• You can use the same label as the jump destination for more than one JUMP instruction.
• You can set only a label in a network, or you can set both programming and a label in a network.
• You must use either a BOOL or SAFEBOOL execution condition for the JUMP instruction.
If you connect an execution condition with any other data type, a building error will occur.
• You cannot omit labels. If you omit a label, a building error will occur.
• Place the JUMP instruction and label in the same POU.
• Programming between the JUMP instruction and the label is not executed when the JUMP instruction
is executed. The outputs retain the values that they had just before the JUMP instruction was exe-
cuted.
