Fig.6-5: Shortcuts for the VDP 16.1BK and VDP 40.1BI keys
Eight M-keys (machine function keys, see
VDP 16.1BK and VDP 40.1BI" on page
left side of the display. The keys on the right side of the display are labeled with
R1 to R8, the keys on the left side of the display with L1 to L8.
The state of the M-keys can be read out in different ways:
● Pressed M-keys are transmitted as PS/2 signals to the PC.
● They can be transferred to a soft control installed on the PC via the serial
interface COM3.
● At last, the signals are output at the optional plug XDP as outputs of a
PROFIBUS DP slave.
The following key codes are output:

M-Keys may not be subject to a repeating operation (Key Controller -> Conti.
Jogging of axes].
The states of the M-keys can be transferred to a soft control via the serial in‐
terface COM3. The soft control has to send a request telegram and receives a
keyboard telegram containing all key states as response. The request telegram
has to consist of one byte with the value 0xB2. The keyboard telegram is sent
not later than 10 ms after receiving the request telegram. Pressed M-keys have
the value "0", keys not pressed have the value "1". The keyboard telegram is
structured as follows:
