Hello Luka; I agree with Huggy's idea of a gateway to DALI, and I offer a suggestion: a Wago Profibus-DP coupler with a DALI multi-master module. The Profibus coupler does not require programming (Wago uses Codesys for their CPUs, but none for the couplers, which act as remote IO nodes); Step 7 is used to configure the Profibus node. There is a requirement for an additional software for the DALI module, a downloadable DALI Configurator. Have a look at these documents, to get an idea of the Wago offer: Configurating a Profibus-DP node using Step7 and WAGO-I/O components (Application Note) WAGO DALI Configurator (Download)
You will have to discuss pricing and availability with your nearest Wago rep. Hope this helps, Daniel Chartier

Hello Luka; What you seem to be looking for is a local (per light control) digital to DALI converter, that you could control with the digital outputs of your PLC. Am I correct?. I have been able to find no unit corresponding to that description. It kind of contradicts the basic design of DALI as a bus addressable lighting control system (see attached picture). You will find more details on DALI lines, controllers, power supplies and control software in the following links (these are from Clipsal, oher manufactuirers of DALI products such as Cpooper, Altenburger, Villalighting...have similar products): http://www1.clipsal.com/dalicontrol/about_dali/what_is_a_dali_line http://updates.clipsal.com/ClipsalOnline/Files/Brochures/W0001030.pdf http://www1.clipsal.com/dalicontrol/products/dali_control_products I found this developer from Germany that proposes a S7 library of functions (valid for the S7-1200) and a gateway to DALI lines, but this gateway takes the place of a DALI controller (in the attached schematic) and controls up to 64 DALI ballasts and lights. It allows the PLC to act as the controlling software for the DALI bus. http://www.nft-systeme.de./index.php/en/products/s7-dali-gateway-ethernet Do you have any design documents we could look at for your project? Why could you not take advantage of the DALI bus schemes ionstead of repacing them with the PLC? Hope this helps, Daniel Chartier |

Hello jnativ; If you decide to look at Hati's suggestion for the ET 200SP CM 1xDALI module, here is some of the available documentation: Sales and delivery release of CM 1xDALI for SIMATIC ET 200SP https://support.industry.siemens.com/cs/ww/en/view/109769177 ET 200SP Communication module CM 1xDALI (6ES7137-6CA00-0BU0) manual https://support.industry.siemens.com/cs/ww/en/view/109769428 Library for ET 200SP CM 1xDALI https://support.industry.siemens.com/cs/ww/en/view/109767048 Library for PROFINET data records (The CM 1xDALI is marked as associated to this library). https://support.industry.siemens.com/cs/ww/en/view/109753067 Hope this helps, Daniel Chartier |
