5.4.2 Analog I/O Modules
All analog I/O modules have 2 bytes of extendable parameterization
information, which serves for the identification on the internal bus and the
structure of the mapping table. With analog inputs 2 bytes follow which are
reserved for future options. Modules with diagnostics capability allow the
diagnostics message to be suppressed or released channel for channel.
Analog outputs contain 2 bytes of parameterization data per channel. In this
case the substitute values are saved for the respective channels.
