Bar

Purpose
The bar is a dynamic display object. The bar displays a value from the PLC as a rectangular
area. The operator at the HMI device can thus see immediately how far the current value is
from the configured limit value or whether a set point value has been reached. The bar can
display values such as fill levels or batch counts.
Layout
The layout of the bar is set in the user program. In the bar, for example, lines can identify the
configured limit values. Color changes can signal when a limit value has been exceeded or
are not met.
Operation
The bar is for display only and cannot be controlled by the operator.
