Sigmatek - Freedom of movement for system operators
Sigmatek has developed the wireless roaming feature for wireless HMIs. The operating solution consists of a wireless panel from the 'HGW 1033' series with safety elements (SIL 3/PL e), the 'BWH 001' base station as an access point and charging station and an 'S-Dias-Safety' controller. Safety and user data are transmitted simultaneously via two WLAN frequencies - 2.4 and 5 GHz. Safety-relevant data is transmitted via the black channel principle. The panel is connected directly to the selected machine and safety controller, with the base station serving as a communication bridge between the wireless and wired network. The interfaces of the base stations are combined to form bridges and all network participants are connected to each other via a single subnet. Operators connect wirelessly to the desired machine or system section at the panel. The integrated OPC UA interface is used to integrate the operating solution into the control system or to exchange data with existing control systems from other manufacturers.
