Logic Modules for Controlling Industry and Building Systems

The Siemens Industry Automation Division has developed new Logo! basic devices. The logic modules of the 0BA6 series are significantly more powerful than their predecessor models. With 200 function blocks, the memory capacity is fifty percent larger than before, and the analog inputs have been doubled to four. The new devices have four high-speed counters up to five kilohertz and are equipped with Teleservice functions as well as ten menu languages. The new separate text display tailored to the logic modules deserves special mention. It can be connected direct to the basic device or installed up to ten meters away.

The new Logo! logic modules of the 0BA6 series are suitable for universal use in industry and in building systems. Diverse applications are possible, ranging from lighting controls, car washes and access controls, through aquarium systems, trash compactors, strapping machines, axle lubrication systems on trains, and feeding systems in cattle rearing, right up to pressure intensifiers and pumping stations.

The new text display has four lines with twelve characters each. Fifty different four-line messages can be configured, with expanded display options such as ticker text, bar graph or toggle parameters. Up to 32 characters per line can be stored for continuous ticker text, for example. The display on the external text display is independent of that on the internal text display. For example, messages relevant to operation can be displayed on the separate text display, and service-related information can be displayed in the control cabinet.

The new logic modules and the internal and external display are configured with the Logo! Soft Comfort V6 standard software. New function blocks for arithmetic and pulse width modulation expand the application options. The Teleservice function simplifies device control and troubleshooting for service purposes. To upgrade existing systems with earlier Logo! generations, only the basic devices have to be renewed. The installed expansion and communication modules can be reused, as can already created programs.
