5.2.2 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.
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.
