The student investigates the connection of sensors and actuators with the AS-i interface in the SPC. This requires a process field bus-capable SPC, which is not included in the setup.

Educational objectives

  • Operate the SPC
  • Connect the devices with the TIA portal
  • Creating programs.
  • Connection of AS interface devices.
  • Testing the programs.

With the actuator sensor interface (AS-i), all you need is an unshielded two-wire cable to connect all sensors and actuators with the controller. The system is clearly organised and easy to install thanks to the cut-clamp technique. The teaching packet consists of:

  • DP/AS-i communication assembly
  • AS-i connection module 2E/2A
  • Process field bus cable
  • Button and indicator lamp

School experiments according to tasks in the experiment handbook.

Target Group
Students completing vocational training in electrical engineering for a trade or industry are the target group addressed. The course is geared toward intermediate learners. So prior knowledge is recommended:

  • Basics of contactor controls
  • Programming of SPC
  • Instruction in the dangers of electrical technology


  • Programming of an SPC
  • Connection of AS–i components
  • Programming methods LAD, SFC, STL, S7-GRAPH
