At the Bauma 2022 in Munich, Germany, Griessbach presented customer-specific operating systems for the construction industry as well as developments in control, switching, and lighting technology. All featuring CAN.
The complete solutions are characterized by high functionality and an ergonomic device design that can withstand the harsh conditions of outdoor use, explained the company in its press release. Scalable diagnostic functions for voltage monitoring and function control as well as optional redundant interconnection of pushbuttons and pushbutton groups are provided for reliability. Touch fields and finger-guiding elements are also integrated if required.
In addition to complete operating units, the manufacturer also showed at the exhibition the current hardware architecture with a 32-bit controller. The controller unit offers storage capacity to implement custom protocols and bandwidth for data communication with different serial networks such as CAN. Software stacks with the complete protocol range of CAN, CANopen, or J1939 can be played directly and configured to customer specific requirements. The other exhibition program included CAN pushbutton modules in the versions Basic, Pro, and Safety-Plus for operating decentralized machine functions. Available with 4 to 12 input fields, these keypads are designed for snap-in assembly and network connection via CANopen and J1939. Additionally, they are also available in variants with RGB LEDs for symbol backlight as well as circular ring or segment lighting in traffic light colors. The Safety Plus modules reach performance level C and are suitable for use in areas of functional safety. Another presented product of the company was their newly-developed CAN rotary encoder module.
