Logic Command/Analog Reference Definition
The Logic Command and Analog reference values are defined within the
product manuals of the connected SCANport device(s).
Defaults
Each I/O module has default values associated with it. At default, each module
generates inputs/status and expects outputs/configuration.
The default values refect the maximum number of read/write words.
You can change the I/O data size for a module by reducing the number of words
mapped into the adapter module, as shown in optimal sizes.
