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 Im-
age.
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.
