What can LOGO! do?
You can use LOGO! for domestic and installation engineer-
ing tasks (e.g. stairway lighting, external lighting, sun
blinds, shutters, shop window lighting etc.), switch cabinet
engineering and mechanical and apparatus engineering
(e.g. gate control systems, ventilation systems, or rainwa-
ter pumps etc.).
You can also use LOGO! for specific control systems in
conservatories or greenhouses, for signal preparation in
control systems and, with the ASi variant, you can have
on-site centralized control of machines and processes.
There are special variants without an operating unit for se-
rial applications in the construction of small machines, ap-
paratus and control cabinets and the field of installation.
