Control with LOGO! 8 230 V

System
Programming a small controller on LOGO! 8 from Siemens. The student should learn the main functions of small controllers.

Objectives

• Create programs
• Learn logistics and control functions
• Test the programs
• Configuring network connections

System
Experiment plate system with all necessary digital inputs and outputs and the necessary interfaces. The inputs can be reached via 4 mm safety connectors for 230 V and via installed circuits with notching and push function. The outputs are configured as potential-free relay contacts and are accessible via safety connectors on the front. There is the option to permanently position the connectors with bridging plugs at 230 V. The controller has an ethernet interface that is constructed as RJ 45. The control voltage amounts to 230 V AC

Methods
School experiments according to tasks in the experiment handbook.

• Operating a small controller
• Wiring
• Create a program
• Function review
