When using the equals condition ("=") for any type of incoming value, TopView looks for exact matches. Set the alarm conditions to match the values from the data source.

TopView does not make assumptions about how to interpret Boolean signals, especially when they are represented as numbers, since different systems may have different definitions for "0" or "1".

One way to confirm the values in your system is to use the TopView Configurator's "Get Values" function in Tags & Limits list. Then set up your alarm conditions to match these values.
