In order to guarantee high quality visualization, the HMI is equipped with a 10.1" capacitive touchscreen which can be operated as a real Multitouch.
The DualCore processor and the 3500mAh battery with a running time of up to 4 hours ensure the long-term and smooth performance and with a weight of only 1400g nothing stands in the way of effortless and comfortable operation.
Mobility plays an important role in many workplaces. Safety functions are indispensable to make visualization comfortable and yet safe. For this reason, the hand-held pendant station is equipped with an emergency stop and an enabling switch. It also has a safety TUV Rheinland certification and country-specific radio approvals in Europe, Japan, the USA and Canada and complies with the safety standards according to SIL3 and Kat4/PLe.
Modern systems must be fast and reliable to ensure optimal working conditions and therefore high efficiency. In order to ensure maximum availability with short response times and to be able to meet the response times required in a security environment, data for visualization and security are separated.
While a WiFi connection ensures data exchange between the hand-held pendant station and the "Connection Box" during visualization, safety data is transmitted via a Bluetooth connection. This division of data flows ensures maximum stability and increases security, as intrusion from outside is made even more difficult.
In addition, it is guaranteed that the maximum permitted follow-up time of an emergency stop signal of 100 ms is not exceeded and that even a temporary failure of the application would not trigger an emergency stop or set the enabling switch to inactive. Interferences can thus be avoided and efficiency increased.
If required, the HMI can also be used in tablet mode if the emergency stop and enabling switch are inactive. If this mode is not desired, a local radio mode is created just after pairing with the base station.
The idea of giving the user more flexibility was not only realized by increasing the freedom of movement when operating the hand-held pendant station, but can also be seen in its simple installation and integration. Thanks to Windows 10, Multitouch and optional HMI software, all options for integration into the workstation are available. Due to its discrete safety outputs, the manual control unit is suitable for any control system. Even retrofit solutions can be implemented.
The local WiFi of the base station can only be found by a KeTop T15x and is not visible for other devices.
In order to comply with the security guidelines, there is also the option of deactivating the WiFi before and after pairing/unpairing. Therefore, no dedicated security bus system is required and existing security solutions and WiFi infrastructures can be used.
Effective range restriction for maximum safety
The wireless design of the HMI allows maximum freedom of movement when operating a machine within its working range. The WiFi and Bluetooth connections provide the basis for determining the permitted distance. Without having to install tags or other components, the user defines a maximum permitted distance from the application and thus creates a theoretical circle around the base station that limits the effective range. This area is independent of how far the radio signal would reach, but refers to the insight into the danger zone.
If the operating range is left, the operator is within a tolerance range and receives a warning by vibration of the operating device and pulsating emergency stop. In this area, the machine can still be operated for a configurable period of time in order not to interrupt the workflow and to avoid frequent shutdowns.
However, if this tolerance range is exceeded, or if the operator does not return to the effective range within the permitted time frame, approval is withdrawn and an automatic emergency stop is triggered. This ensures that the machine can only be operated if the user has visual contact to the machine and thus can react to any danger immediately.
Comfort, reliability, simple integration, and above all security - this is what the KeTop T15x Safe Wireless stands for.
The visualization solution offers you, the user, numerous options for customizing the user interface and thus provides a powerful basis for the individual configuration of machines. All modules and the application frame can be pre-defined and put together as desired, and the components can be reused for individual machine models. The HMI application and keyboard can be individually designed and configured. It is also possible to change fonts, units, symbols, date and time to make operation as convenient as possible.
The user interface is designed so that you can create and customize your own controls. It is possible to display and configure time-controlled animations. A gesture control for an intuitive working method was also developed. The combination of openness and configurable functionality makes this visualization concept an extremely adaptable and customer-friendly application. Whether self-written functions, company-owned visualization or own libraries - there are no limits to the design of the software.
