In byte 2, a status transmits the following meaning:
Value

0x01
0x02
Fig.6-8:
Status byte
Value 0x01 means that during the self test executed directly after the reset, a
M-key was recognized as pressed. As, however, after a reset no key is activa‐
ted, thus, a defective key can be recognized. In byte 3 a CRC 1) is transmitted.
To calculate byte 3, byte 0 is linked bit-by-bit with byte 1 by XOR. Then, the
result is linked bit-by-bit with byte 2 by XOR. After that, this result is transferred
as CRC in byte 3.
The M-keys are output at the optionally provided connection XDP (see
7.1.10 "PROFIBUS DP Interface" on page
DP slave, so that they can be read as inputs by a connected PROFIBUS DP
master. The corresponding GSD file is stored in folder "C:\SUPPORT
\PROFIBUS". Pressed M-keys have the value "1", key not pressed have the
value "0".
