Lookout OPC reads A-B PLC Output word bit 15 as negative.

[Rex]

I am using LabVIEW and Lookout OPC driver to read an output word from an Allen-Bradley PLC and display the bit values as booleans. When bit 15 goes to a logic one, the value the opc driver reads goes negative. this causes the Labview Number to boolean array converter to 'mis-read' the bit values. How can I prevent this mis-read?

I dealt with this problem a couple of years ago.
I had to write a VI that decode the bits and fixed it.
THe VI just checked the MSB and acted accordingly.
