I have a PLC tag 'Bits' this is a BOOL[128]. Is there a way to get the OPC tag browser to recognize this as a 128 bit tag? Currently it is broken into 4 sections of 32 bits each. So the tag Bits[100] in the PLC is actually Bits[3].4 in ignition.

There is not currently any way to make this work.

Logix PLCs represent BOOL arrays / bits internally as arrays of DINT, and they do not provide any mechanism by which an external client can determine whether the tag is a BOOL/BIT array or a DINT array.

Some future version of our Logix driver may include a setting to always treat DINT array as BOOL array, but right now it's always a DINT array.

Check for `DWORD` or dword arrays.

Oops, I think I mixed up DINT and DWORD.
