Inserting Blocks

To insert blocks on the network apply one of the following options:

• Select a contact, connection or block then click Scheme>Object>New>Block, which causes a dialog box to appear listing all the objects of the project, then choose one item from the list.
• Drag the selected object (from the Workspace window, the Libraries window or the local variables editor) over the desired connection.

If the object has at least one BOOL input and one BOOL output pins, they will be con- nected to the power link (and it will possible to add EN/ENO pins later with the provided command); otherwise the EN/ENO pins will be automatically added.Operators, functions and function blocks can only be inserted into an LD network on the main power link, or on the power link of a branch (so they can not be inserted on the par- allel of a contact); it is also not possible to create a contact in parallel of a block.If a block has a BOOL input pin, it is possible to create another logical sub-network of contacts and blocks before it; otherwise, you can connect only variables, constants or expressions (that nevertheless can be connected to BOOL pins) to non-BOOL input pins.
