2 AO I/O modules
All analog modules have 6 bytes of extended parameterisation information and
offer the possibility of switching in parameterisable substitute values in the
case of a master failure.

If, in the case of a PROFIBUS-DP fault, the
switching of substitute values is enabled by the
bus coupler parameterisation, this data is trans-
mitted to the periphery in the case of a fault.
