I have a ControlLogix L65 controller, and I'm trying to read some alarm status information from a BMS gateway device. The problem is that this data is contained in a bit array, and you can't read BOOLs using MSGs. The only answers I've found are that the BOOLs on the source device must be converted to integer. It would be a considerable amount of hassle if I needed to modify the BMS device configuration (never worked with it, probably would impact other systems, and it's likely nobody at this site knows anything about the configuration of this device, so it'd be a whole thing), so I would very much prefer NOT having to do this. Is there any possible way to have the source element on a CIP Data Table Read be a bit array? I've tried writing to DINTs, but no matter how I address it I get the '2107' data type mismatch error.
