INDUSTRIAL COMMUNICATION Showing true color Elisabeth Vatter If painters want to operate the corresponding paint supply systems in spray booths, explosion-proof solutions must be found. A german company is further enhancing its systems with a modern key panel which already meets explosion protection requirements in its standard version. The highlight: Installation, programming and operation offer significant benefits compared to the previous solution. About Company name: Siemens Digital Factory Division Headquarters: Nuremberg, Germany Employees: more than 100,000 Products and systems: motion control system Simotion, CNC automation system Sinumerik, drives family Sinamics, industrial automation systems Simatic and customer services Systems for the processing of wet paint are manufactured in the surface technology department of the company. “We are putting a lot of emphasis on the high technical availability and dosing accuracy of our plants,” explains the product manager at Oltrogge & Co. KG in Bielefeld, Germany. Under the name Regular, the systems are available in 15, 30, 50 and 100 versions depending on size and type. To meet their own requirements for innovation and quality, in the summer of 2013 management decided to use the key panel KP8 PN from Siemens. It replaces the generally mechanical pushbutton solution used until now. Time savings during installation Explosion protection has top priority in paint sections. The individual processes for spraying in the booth as well as the selection of recipes takes place via remote control from the control cabinet located outside the painting section. Remote control must be rather clearly structured and easy to operate for the painters. “The modern control panel meets all these attributes and even offers a number of benefits as part of automation,” explains Dirk Schöning, technical manager at Bosmann Elektrotechnik GmbH & Co. KG in Werther, near Bielefeld. In addition to building the control cabinets, the company is in charge of the Author: Elisabeth Vatter, Digital Factory, Siemens AG, Nürnberg, Germany AUTOMATION TECHNOLOGIES 2/2015

Bosmann was there from the very beginning for the development of the 2K dosing and mixing systems and is therefore very familiar with the requirements of the system manufacturer. Wolfgang Rosteck: “Coating technology is a highly competitive market in which we want to set ourselves apart with our technical innovations.” The new key panel accomplishes this goal because it offers a series of benefits. The manufacturer points out that it was able to reduce the time for installation alone by 60 % compared to other solutions. The reason: The devices that are ready for installation can be connected to Profinet in no time thanks to the two RJ45 ports on the back of the housing with an integrated switch. A special connecting cable not only establishes the communication between the devices, it also provides the 24 VDC power supply. Modern visualization and operation The devices have seven digital inputs and seven digital outputs that are freely programmable. Design engineers can use these inputs and outputs to include a seven-segment display that shows numbers from 0 to 9 in their plans for recipe selection. Dirk Schöning explains: “The operating convenience of these key panels represents real progress for automation 01 The assignment of the keys and their different colors takes place by means of TIA Portal and is then transferred to the signaling column AUTOMATION TECHNOLOGIES 2/2015
