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). For modules with diagnostic bit is set, also the
data bits have to 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.

750-523
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".
