display. The keys on the right of the display are labeled with R1 to R8, the
keys on the left side of the display with L1 to L8.
Addressing M-keys
The M-key state can be retrieved differently:
● Pressed M-keys are transmitted as USB keyboard signals to the PC.
● The M-keys transferred to the control cabinet PC via the serial
connection of the CDI interface are bit-coded and can either be output
via a Profibus-DP slave card or retrieved via a connector strip and
transmitted to the corresponding extension card. The transmission
protocol is ensured by the hardware. If there are interferences or if the
connection is interrupted, the incoming M-key bits are disabled after 10
ms.
Requesting M-keys via Windows applications
The following key codes are transmitted to the operating system:

If a USB special keyboard is used, the incoming keyboard data
stream is analyzed and if a M-key code is detected (F13-F24 or
four OEM special characters) the corresponding Ctrl-LRShift-Alt-
<n> code is inserted into the data stream, see
"IndraControl VDP 16.3/40.3/60.3/90.3/92.3" on page
M-key output via Profibus DP (only for devices with CDI interface)
The M-keys can be output via an optional PCI plug-in card in the PC. The
corresponding GSD file is delivered with the application. If M-keys are
pressed, their value is one "1", otherwise "0".
