Yes, flexyPage displays can be installed horizontally as well as vertically.

We only use displays matching the industry standard. They have a wide viewing angle (> 160°) in all directions. In addition we offer anti-glare plexiglass and safety glass for protection. This way the displayed content can be viewed well from all sides. 

When installing the display, the rotation of the display can be changed in 90° steps in the menu. All applied widgets will adapt in orientation and scale right away. In the web editor all elements can be newly aligned and set up.

The displays are communicating with the I/O-modules via CAN-open messages, which are defined in the CAN-open Lift standard. The modules of all manufacturers supporting this standard can be used. On the market, these modules are offered with 8, 16 or 32 I/Os and some of them can also be extended with more I/Os. 

Directly via the CAN-bus there can be up to 63 modules (64 minus number of displays) connected. This should not be necessary very often in practice. Each module theoretically could supply up to 128 signals. Thanks to the possibility of connecting a repeater to the network, there is basically no limit to how many I/Os can be connected.

When it gets to the display's configuration of these signals, it looks differently though. To be able to design the configuration of the signals clearly, we limited the number of configurable I/Os to 127. This should be more than enough in most cases. These 127 signals can be distributed freely among one or many modules, which also can be located on different places in the lift depending on where the signals are available (e.g. one module on top of the cabin, one in the controlling).

In addition to the I/O signals, the display can also directly evaluate the sensor data of various sensors. This way e.g. the current load can be displayed in kilogramm or the position and velocity of the cabin, without needing I/O-modules.

In the figure below, the general wiring of an I/O-module with 16 I/Os is depicted. More possibilities of Connecting various I/O modules, displays and sensors can be found in the installation section.

If you like to link more than one display, you only have to connect the CAN-bus and LAN interfaces of the displays. Than you can setup the widgets on the displays in the way you needed for your application. The connected displays act like a single display. 

Setup of two elevator displays

Yes, you can use the flexyPage displays in all existing elevators also if the elevator dosen't support the CANopen-Lift standard. 

To provide the necessary signals to display external I/O modules are used, which are offered by many manufacturers and which are connected via the CAN bus. This has the advantage that the I/O-modules can be installed directly in the control cabinet of the lift controller where the signals are available. For the connection to display only two wires for the CAN bus connection are necessary, which are usually available in the traveling cable even when retrofitting existing elevators. Is it necessary to indicate special sensor data on the display such as the current load, the position or the speed of the car you can connect the required sensors directly to the CAN bus too. The following illustration shows the standard assignment of the inputs / outputs.
