Updating an older M580 application containing a BMENOC0301 to Unity 12 results in a different DDDT structure for the health array.
Issue
Updating an older M580 application containing a BMENOC0301 to Unity 12 results in a different DDDT structure for the health array.
Product Line
BMENOC0301
Environment
Unity, Windows 10
Resolution
Updating an older application containing a BMENOC0301 to Unity 12 results in a different DDT structure for the health array. Prior to Unity 12,
it was defined as an array of the type BYTE. Unity 12 shows the health bits as an array of the type EBOOL. There is no information regarding what the changes
were or how to convert back to the older structure.
The DDT structure was changed in response to many customer requests for simplifying the DDT's to make it easier to use. The WORD structure
was changed to a more comprehensive BOOL structure. This was accomplished by taking advantage of the opportunity from the compatibility
break between the M580 CPU versions V1 to V2.
There is available tool that can be used to reverse the changes because the structure is quite comprehensive.
An explanation of the changes can be found in the online help by searching for the topic 'Standalone
DDT Data Structure for M580 CPUs'.
The differences between the two structures can be found by comaparing the structure for Unity 8 with
that of Unity 12 (reference page 280 and 277 respectively in the attached user manuals)
