Abstract

A control system and a method for mounting a control system, the control system comprising a signal-distribution board, a top-hat rail, at least a first contact device and at least a second contact device. The first contact device and the second contact device are arranged at the signal-distribution board with an offset relative to each other with the signal-distribution board electrically connecting the first contact device to the second contact device for at least transmitting data. The top-hat rail is mechanically fastened to the signal-distribution board and a first coupling module may be mechanically fastened to the top-hat rail, where the second contact device is embodied to electrically contact a signal-processing module or a second coupling module. The first contact device may be electrically connected to a field device.
