To do this, click on the TwinCAT real time server icon and activate the 'Start' command from the 'System' menu.
The color of the icon changes through yellow to green, which means that the TwinCAT real time kernel is active. Starting TwinCAT PLC Control: Start now the programming surface from the TwinCAT PLC.
Monster Curves Reality. Then click with the mouse 'start' ->'programs' ->'TwinCAT system' ->'TwinCAT PLC control'. Open Projekt: A PLC project is stored in a file on the hard disk or on a diskette that bears the name of the project. To open a project, select the 'File' menu item and then the 'Open' command. Select directory: Switch to the directory specified above by clicking the symbol shown on the left in the dialog box. Double click the 'Samples' entry. Then proceed in exactly the same way with the 'First steps' entry.

Items of the PLC Control: After opening Maschine.pro select the POU (programm object) MAIN and make a double click with the left mouse button. The following dialog box opens: In the upper blue beam the project name Maschine.pro is located. Among them there´s the command menu and the toolbar. The lowest grey beam contains the status line.
The dialog window divides into three individual windows, it contains the object list, the variable declaration and the program representation. Object list: TwinCAT distinguishes three kinds of basic objects in a project: (Program) Blocks Data Types Resources Variable declaration: A PLC program stores its data in variables. Variables are comparable to flag words or data words. Before a variable can be used, it must be declared, i.e. Its affiliation to a specific data type (e.g. BYTE or REAL) must be made known. Declaration also involves defining specific attributes such as battery buffering, initial values or affiliation to physical addresses.
If a variable is not needed in the input or output image, i.e. Only within the PLC program, the PLC programmer need not worry about the storage location of the data. Import Maps From Gmapsupp.img.
This is taken care of by TwinCAT. This avoids unintentional overlapping of flag words/data words as was possible in previous systems (side effects). As in the case of variables, function blocks also have to be declared (instance). In the example, one instance each (drive, down and up) of the three functions 'DriveType', 'DownType' and 'UpType' are created. After instancing, the instances can be used and can be activated.
