PROBLEM TO BE SOLVED: To provide a diagram debugging system of a programmable controller, which easily debugs a diagram having nodes including branch points of a control program in operation. SOLUTION: A programming apparatus includes: a control program edit processing part 11a for preparing a control program for generating first instruction/first inner variable for specifying connection or non-connection/connection destination of one input side of a node, for the node connecting between symbols and second instruction/second inner variable for specifying connection or non-connection/connection destination of the other output side of the node; and a wire force processing part 11b for commanding to rewrite the first instruction/first inner variable into third instruction/third inner variable respectively, rewrite either the third instruction/third inner variable, and the second instruction/second inner variable into fourth instruction/fourth inner variable respectively, and rewrite either the fourth instruction/fourth inner variable.
