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 needi…

I think the prevailing opinion is to create a separate tag for each bit [image] Tag Type Boolean Array to set up Alarm Bit State. Am I doing it right? Ignition Have you tried just a plain integer? Non-array? You can write a script to create these tags Import bit ala…

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!
