VarOut2 is set to FALSE, if VarIn2 delivers TRUE. VarOut1 retains this value, even when VarIn1 springs back to FALSE. VarOut1 is set to TRUE, if VarIn1 delivers TRUE. The symbol for Set is S and for Reset is R. This command can only be used for selected inputs of the element output (Cursor position 3). The output of the element block or input is negated when it is selected (Cursor position 4).Ī negation can be deleted by negating again. The input of the element block, output, jump or return is negated when it is selected (Cursor position 3) The symbol for the negation is a small cross on the connection. This command is used to negate inputs, outputs, jumps or RETURN commands. They differ from the normal in- and outputs of POUs by the way they are displayed and in that they have no position index. They are used for inserting in- or out-pins as in- and outputs of the macro. These commands are available as soon as a macro is opened for editing. To increase the number of inputs for such an operator by one, the operator itself must be selected (Cursor position 1). The number of inputs is variable for many operators (e.g. This command is used to insert a block input. You obtain a new line within the comment with +. This command is used to insert a comment. Note that in Online mode a jump label with the name RETURN is automatically inserted in the first column and after the last element in the editor in stepping, it is automatically jumped to before execution leaves the POU. This command is used to insert a RETURN command. The jump is inserted using the command ' Insert 'Jump' In Online mode a RETURN label for marking the end of POU is automatically inserted. The text offered "?" can be selected and replaced by the jump label. The jump label is inserted using the command 'Insert 'Label' ![]() The text offered "?" can be selected and replaced by the jump label to which the program should jump. The value which is associated with the input of the output is allocated to this variable. The input assistance can also be used here. The text offered "?" can be selected and replaced by a variable. This command is used to insert an output. The text offered "?" can be selected and replaced by a variable or constant. If the new block has a smaller highest number of inputs, the last inputs will be deleted. If the new block has another minimum number of inputs, these will be attached. The input assistance serves to select the desired block from the list of supported blocks. This can be converted by Selection and Overwrite of the text into every other operator, into every function, into every function block and every program. First of all, it is always pasted in as an "AND" operator. This command can be used to paste in operators, functions, function blocks and programs. Outputs for the elements block and input: Inputs for the elements block, input, output, jump and return:Ĥ. Text fields for the elements blocks, input, output, jump, label, return and comments as well as text fields for connection markers:ģ. Trunks of the elements blocks, input, output, jump, label, return and comments.Ģ. The following is a list of all possible cursor positions with examples:ġ. In all other cases the current cursor position is shown by a rectangle made up of points. The selected text is shaded in blue and can be modified. ![]() The most important commands can be found in the context menuĬursor positions in the continuous function chart editor CFCĮach text is a possible cursor position. One advantage of the continuous function chart as opposed to the usual function block diagram FBD editor is the fact that feedback paths can be inserted directly. This line will be converted into a connecting line just as soon as space is available. If the case arises where a connecting line cannot be drawn simply because of lack of space, a red line will be shown between the input and the associated output instead. ![]() The connecting lines are automatically adjusted when the elements are moved. The shortest possible connection line is drawn taking into account existing connections. The connecting line will be drawn automatically. The inputs and outputs of these elements can be connected by dragging a connection with the mouse. Elements of the sequential processing list include blocks, input, output, jump, label, return and comments. No snap grid is used for the continuous function chart editor so the elements can be placed anywhere. It looks like a block which has been produced using the continuous function chart editor (CFC):
