10.5. Create Ladder Diagram Introduction Creating Ladder diagram consists of 'drawing' program lines with input contacts or functions and output relays or functions placed between 2 vertical Power Rails. The two rails can be considered as electrical wires between which items are placed. The lines as a whole represent your local automation. In the LD Toolbar click - - to insert a new Ladder Line. In the window of Ladder programming, a rectangle appears with a line number. Only one line at a time can be edited with only one rung (a rung is a set of Input conditions connected to only one set of Outputs). The grid shows you the places where you can place contacts, relays and functions. The Ladder is executed from left to right and from top to bottom. Every contact, functions and relay is treated when it is read. Be careful when using an output at different places of the Ladder, unless you do SET and RESET. To help you, check the Cross reference of the Tags. figure 19 According to the item you wish to use, select the proper icon in the Toolbar. TWinSoft: 8.32 – Getting Started 30
Inserting items When inserting an item, you must declare the variable(s) associated to it: Digital Tag for a contact and a relay, Digital or Analog Tags for Functions. You have to work with Tags; it is not possible to select the number of a register in the list of registers. A Tag (local or global) can be created while inserting an item. There are two possibilities to select a Tag: The Tag exists The Tag does not exist - You know the name of the Tag: you type its name. TWinSoft is not case sensitive, so you can type it in capital or small letters. - You don’t know the name of the Tag: you click the button to open the list of Tags. You have the choice between Global Tag, Local Tag and Special registers (see previous chapter ‘Variables’). You type its name and press to create it. The Tag can be either Local Tag or Global Tag (see previous chapter ‘Variables’). According to the field you are in, you can select a Tag or type a constant. A constant is a 16-bit variable that will be considered as Signed (-32768 -> 32767) or Unsigned (0 and 65535) according to the Function where it is used. The colors of the Tags The color used to display the Tag in Ladder programming informs you of its type: Black: Global Tag. Blue: Local Tag. Brown: Special register (analog or digital) it is always considered as Global Tag The Keys To compile a line. Use also the icon - When a line is selected: to quit edit mode. Use also the icon . - When an item is selected: to release the item and return to selection mode (arrow). - When Tag box is opened: to carry on without specifying a Tag. '???' will be inserted instead. To enter a Tag afterwards, double click '??? ' To delete the selected item. TWinSoft: 8.32 – Getting Started 31
