Engineering of a SIMATIC ET 200AL with IO-link

  • Entry
  • Associated product(s)
The SIMATIC ET 200AL has a high IP65/67 degree of protection, a particularly compact design, a small space requirement and low weight. It has been specially designed for distributed control electronics in confined spaces and applications involving motion.

SIMATIC ET 200AL modules can easily be installed in any position. They are mounted directly in a machine or assembly line on site, where they use M8 or M12 connections to connect sensors and actuators.

In combination with IO-Link, even wiring can be reduced.

The IO-Link at a field level makes for much easier integration of all components and provides maximum transparency and efficiency with regard to the final meters of the process – thus ensuring seamless communication.


 

A SIMATIC S7-1500 control is used as an IO controller. The ET 200AL interface module and the CM 4xIO link are installed in the field and connected to the IO controller via PROFINET.

To operate the machine on-site, the SIRIUS ACT control devices are used, which are connected via IO-Link to the ET 200AL. These so-called IO-Link electronics modules are fitted into the housings of the control devices, which convert the signals of the control devices to IO-Link.

The electronic module in the upper housing has 8 inputs/outputs that are freely programmable via the PCT (Port Configuration Tool). The default setting of 6 inputs and 2 outputs is suitable for this application example.

A permission control for the operation of the machine is realized with the SIRIUS ACT ID key switch. In addition to the permission level, each ID key has a unique identification number. This identification number is read out when the ID key is placed in the user program and is saved in a data block along with a timestamp.

This sample application contains the following descriptions:

  • Configuring an ET 200AL and a CM 4xIO-Link in the TIA Portal

  • Configuring the IO-Link master (CM 4xIO-Link) and IO-Link devices in the PCT (Port Configuration Tool)

  • Incorporating the signals of the IO-Link control devices in the user program

  • Logging IDs of the inserted ID key with a timestamp
