Notes:
1. The ControlNet module uses a ControlNet 32-bit run/idle header, so the actual data from the module will
always start with word 2 (the third word) of the data. The first 2 words, at 16 bits each, are the ControlNet
run/idle header. To mask off the run/idle header for clarity, create a user defined type with 2 members -
HEADER, type DINT; and DATA, type INT with ‘input assembly size - 2’. Copy the data from the actual input tag
to a tag of this structure, and then reference the structure's DATA member using the element numbers in your
documentation.
2. There will always be a configuration tag of type AB:ControlNet_MODULE:C:0 created for this module, which
has one member called Data, of type SINT[400]. This SINT[400] tag is created regardless of the configuration
size, which can range from 0 to 400 bytes (SINTs). Since a data size of zero is specified, no data will be sent to
the module.
