Anyone who installs a modern display in an industrial application is dependent on a variety of interfaces and protocols. This is because the days when operating devices largely stood alone are over. They are now integrated into a comprehensive network of other devices, control systems and components with different functions. Interfaces of all kinds ensure correct and smooth communication between all participants. CAN and Ethernet connections are implemented via these interfaces, and video and audio inputs, USB connections and I/O interfaces are also essential nowadays. The operating device manufacturer Graf-Syteco relies on a wide range of possible interfaces in its GSt-A series displays. The right hardware is of particular importance here, as it forms the basis for the use of industry-standard protocols.

Displays for every application

While the GSt-A043 and GSt-A073C displays impress with their compactness in space-saving applications and, above all, mobile machines, the GSt-A070, GSt-A101 and GSt-A123 comfort devices offer a wide range of options from interfaces and protocols for individual solutions. Thanks to their robust design, they are equipped for use in mobile machines and outdoor areas, and the LED button lighting can be controlled individually. All Graf-Syteco systems have a 5-pin connector for CAN and Ethernet connection as standard. A data volume of up to one gigabit per second is possible via the Ethernet interface. The in-house and AI-based safety assistance system BirdView is also connected via Ethernet. As an option, the displays can be equipped with a 26-pin connector, which offers an I/O connection and up to three CAN interfaces for external applications. This is particularly relevant when reading out motor data and add-on motors. The CAN FD interface is the right solution for those who need to transfer large amounts of data.

However, modern displays require additional interfaces to ensure safe and efficient operation: Graf-Syteco offers this with the USB connection, which can be used to install and configure the tried-and-tested GSe-VISU and openSYDE software. It can also be equipped with keyboards, mice and more. Graf-Syteco also equips the GSt-A series with four analog video inputs, an audio output for speaker connection and multifunctional I/O interfaces.

Modern protocols offer smooth communication

Interfaces only develop their full potential if the common protocols for communication are supported. By using standardized protocols, the displays of the GSt-A series fit perfectly into the networked infrastructure of the system. The CAN field bus system plays a central role here. With the GS-CAN specification, Graf-Syteco offers a protocol for variable values on the display. The GSt-A devices are also compatible with the openSYDE software platform for easy configuration and control of mobile machinery. The Tuning-based company also offers the standard use of HTTP, FTP, MQTT, SSL, Modbus TCP, UDP/P, DHC/P and OPC/UA. Graf-Syteco thus equips its operating devices for reliable use in demanding applications - from compact excavators to large material handling cranes.
