AS-Interface

System
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.

Function
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

Methods
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

Topics

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