Digital Output Modules

Digital output modules use one bit of data per channel to control the output of the
corresponding channel. These bits are mapped into the Output Process Image.
Digital output modules with diagnostics have one or more diagnostic bits
available. The diagnostic bits are evaluated by the fieldbus coupler. In the event
of a diagnostic message, the fieldbus coupler enters the state of the diagnostic
bit in the diagnostic status word. The entries in the diagnostic status word are
made channel-specific.
When analog output modules are also present in the node, the digital image data
is always appended after the analog data in the Output Process Image, grouped
into bytes.

In addition to the process value bit in the output process image, the digital output
modules also supply 1 bit that is represented in the input process image. This
status image shows "manual mode".
