I have 26 DINT tags in my Controllogix PLC (832) induvial bits. Each bit represents a possible fault condition thus the use of the DINT to reduce number of tags to be created. In tag browser of Ignition I cannot see to the bit level. Is there a simple way to access the induvial bits without needing to create and map 832 ignition tags?

I think the prevailing opinion is to create a separate tag for each bit

You can write a script to create these tags

I have not used it yet, but there is also a tag import tool on the exchange that might be a better choice

Consider making a UDT that has the 32 bits as member tags.

If each bit is used only for alarming, you have the ability to create multiple alarms on a single integer tag, where each alarm is based on state of individual bits.

I always make a "Dint to Bit" UDT whenever I have cases like this. Something like what @JordanCClark posed would be perfect!
