Bool Tag
Overview
Holds a single true/false value. This is the type to use for anything that's fundamentally a flag or status bit — a robot's "queue empty" signal, a machine's running/stopped state, a connector's own %CONNECTED/%HEARTBEAT status.
Value
true or false.
When a raw value comes in from a device that has no native boolean type (many PLCs and robot controllers only have integers), a numeric 0 is read as false and any non-zero number as true.
Transform Options
BoolTag supports one Transform:
| Transform | Effect |
|---|---|
| NOT | Inverts the value — true becomes false and vice versa. |
NOT takes no argument; entering either NOT or NOT() in the Transform field works.
Example: a device reports 1 when a door is open, but you want the tag to represent "door closed" instead. Setting Transform to NOT flips it so the tag reads true when the door is actually closed.
Type Attributes
BoolTag doesn't use Type Attributes — the field has no effect if set.
Notes
- Capture Changes Only behaves as an exact equality check for BoolTag — there's no tolerance setting to consider, since a value is either the same or it isn't.
