Assigning parameters to the analog inputs / outputs

Operating mode
Parameters are assigned to the operating mode via the m+0 byte (Analog Control Byte 0) of the
output image of the analog outputs:
Byte
m+0
m+1
m+2
m+3
The reserved bits must be preassigned with the value "0".
The operating mode is set to "no operating mode" during power-up, as soon as a valid setting is
made this will be applied and will subsequently no longer be reset. If a reset is initiated by the
user, this is interpreted as an error.
