Constant setting:
– The diagnosis messages are set in
Byte 6 of the process input data (inde-
pendent of "diagnostic"). Byte 6 of the
process output data contains two bits
which may set to flush the transmit- or
the receive-buffer.
– Byte 7 contains the status- or the
control-byte.
– Bytes 0 to 5 contain the user data.
