Resolution: 16 bits includ-
ing sign
Once the CPU has processed the digital signal, a DAC
(digital-to-analog converter) integrated in the analog on-
board I/O module converts the output signal to an ana-
log current or voltage value. The resulting value of the
output signal corresponds to the output value with
which the analog on-board I/O module controls the
analog actuators.

Integrated output types
With the selection of the type of output you specify
whether the digital-to-analog converter is to convert the
output signal into the type of output "Current" or "Volt-
age". The output can be selected by individual channel.
Configurable diagnostics
The analog on-board I/O module can diagnose errors.
The module reports the diagnosed state to the CPU
using a diagnostics error interrupt. Different types of
diagnostics are available that you can parameterize
channel-granularly.
