Communication with S7-CPU via DALI Gateway
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.
An S7-1200 CPU is used in place of all SIMATIC controllers. The figure below shows the most important components for the communication between an S7-1200 CPU and the “multi PROFINET + DALI” gateway by MBS GmbH.
- 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.
