Title: MessageListByBit data types for PLCAddressValue
Post by: scott.clark on October 29, 2015, 12:43:08 PM

using AdvancedHMI v3.99a with AB CompactLogix processor

I would like to use the MessageListByBit control for capturing machine fault conditions.  I like this method because it captures conditions sumultaneously, however I have not found a data type that allows more than a single 32bit double integer.  I have 100 plus fault conditions to capture.   Is there a way to address an array of DINTs?

Also, how do you clear the messages?

Thanks!

The MessageListByBit is still somewhat limited. The MessageDisplayByBit had addressed these limitations by adding additional properties. These new features will eventually be put in the MessageListByBit

To clear the list in code:

MessageListByBit.Items.Clear
