CM 1xDALI library is a SIMATIC CPU program library. You use the CM 1xDALI library to
program for the CM 1xDALI. It helps you easily access CM 1xDALI from the SIMATIC CPU.
CM 1xDALI library can be used on S7-1500 based CPUs (CPU 15xx).
CM 1xDALI library contains several CM 1xDALI function blocks (FB) in the STEP 7. The CM
1xDALI function blocks are collected in several functions groups, such as Addressing
function blocks (Page 32), Control gear dimming function blocks (Page 40), Diagnostic
function blocks (Page 52) and Configuration function blocks (Page 67).

CM 1xDALI data storage model
A DALI device can be a control gear or input device. The term "sensor" refers to the input
device in this documentation.
Each of the CM 1xDALI and DALI devices has its own database to store status and address
information.
The following figure shows the CM 1xDALI data storage model and data flow.
