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.
Some digital modules have an additional diagnostic bit per channel in the Input
Process Image. The diagnostic bit is used for detecting faults that occur (e.g.,
wire breaks and/or short circuits). With some I/O modules, with set diagnostic bit,
additionally the data bits must be evaluated.
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.
For each 8 bits a subindex is occupied.
Each output channel occupies one instance in the Discrete Output Point Object
(Class 0x 66).

The digital output modules deliver 1 bit via a process value Bit in the output
process image, which is illustrated in the input process image. This status image
shows "manual mode".
