3.2 I/O Assembly Object Instance Data Attribute Format
In order to maintain consistency, this device type will only allow connections to
either INT or REAL based assembly instances ( Data Type definition 19).
Once a valid connection is established, attempts to configure connections to a
different type of assembly instance will return an error.
The I/O assembly DATA attribute has the format shown below:
