Use this function to convert your circuit diagram from FBD to LAD.
The following rules apply to the FBD to LAD conversion:
An AND block is converted into a series contact circuit
An OR block is converted into a parallel contact circuit
Comments for basic functions are not applied in LAD, as a basic function is converted into multiple contacts. Thus, the comment cannot be assigned definitely.
In LAD, input comments are assigned to all contacts of this input.
User-defined comments are not included, as their position in the circuit diagram can not be defined based on blocks.
XOR blocks must be converted into corresponding LAD logic consisting of positive and negative contacts.
Note
When converting, the total number of blocks in your circuit program can sometimes increase. This could cause the permitted number of blocks for your LOGO! to be exceeded.
It is therefore not always possible to convert from FBD to LAD.
Remedy: Under Tools > Select Hardware, select the hardware series 0BA6. Start converting to LAD. Then under Tools > Determine LOGO!, see which hardware series is compatible with the circuit program.
