Read AB - ControlLogix Boolean Array Tags

Ignition
,
1

I am trying to read Boolean array tags from Rockwell - Compactguardlogix PLC.using Logix driver.
The tas in plc is ABC[32] - Boolean Array.
This tag is coming in ignition as ABC_0_ , i can directly write interger values 0 -32 , in tag browser , but i am not able to read this tag or write this tag via scripting,
I referred the manual and found that the tag can be ABC[0].1 ....ABC[0].31 , but if i use this tag i am not able to read/write in ignition. whats wrong here ?

  1. Boolean arrays in Logix PLCs are not exposed to the world as actual booleans, but as bits in a DWORD array. 32 booleans per DWORD.

  2. Be sure the boolean array tag in Logix is set to External Access: Read/Write.
