  • Entry
  • Associated product(s)
This application example shows how to configure a communication between a SIMATIC CPU and a DALI network with the help of a gateway.

Please note that a DALI V2 Multimaster module is also available for ET 200SP.
For more information, see the product release 109769177
An application example for the use of this DALI V2 Multimaster module is also available 109771151

Gateways enable the communication between two networks that use different communication protocols.DALI (Digital Addressable Lighting Interface) is a network protocol to control lighting devices in facility automation.
The task is to create a communication connection between a SIMATIC CPU and a DALI device via a PROFINET interface using a DALI gateway.

  • The application example can simply be adjusted to other controller families.
  • The application example can be simply adjusted for plant expansions.
  • Configuring and commissioning the gateways does not require any additional software. Standard tools such as a simple text editor are sufficient. The configuration can be edited directly in the gateway.
