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.

Abstract: A method is disclosed for producing a piston (8) having a circumferential seal in the form of a circular cup seal (16). In a functional, installed state, the cup seal (16) has a profile consisting of a leg held in the piston (8) and aligned radially with respect to the piston longitudinal axis (19) in a radial region (17) and of a leg which is bent by approximately 90° into an axial region (18) and is aligned approximately parallel to the piston longitudinal axis (19). The cup seal (16) is mounted in a mold as a flat or arched preform (21, 21a) with a radial region (17a, 17b) which forms the approximately radial leg, aligned with the piston longitudinal axis (19). A circumferential region (18a, 18b) projecting radially beyond the mold cavity is shaped into the axial region (18) after removing the piston from the mold to obtain the functional contour of the installed state of the cup seal (16).
