Goals and Symptoms

On some equipment, you can have inconsistencies between data in the DDDT type of Advantys equipment when used in Unity Pro.

Example: STB AHI 8321 Module used in an STB island with STB NIP 2x 1x module.


Causes and Fixes

This behavior is normal If the data is not 32-bit aligned that means, if the Primary variable (32 bit data) object is not acquiring addresses like 0,4,8,12 etc...then the M580 master aligns them automatically to the Byte array. So it is necessary to plan the island in such a way that the variables falls at a 32-bit boundary.

Another easier solution consists in Configuration Advantys software for each module to add an alignment parameter, this parameter allows to re-align the variables.


After validation variables become consistent.
