9.5. Picture Displays
9.5.1. Basic Operations
You can use a variable to select and display a predefined picture with a picture display.
A picture display can have up to 256 states. Each state can have a predefined picture. The maximum number of states that
a picture display can have is determined by the state type and the data type of the monitored variable. The following table
shows the maximum in each case.
State Type Type of Variable Maximum
Bit Bit 2
16-bit 256 Value
32-bit 256
16-bit 17 LSB
32-bit 33
Animation Bit 256
Note: This is a special state type that is unique to the picture displays. The bit
variable is used to control the animation. When the bit is on, the animation is
enabled. When the bit is off, the animation is disabled. The animation is
performed by showing the picture of each state one by one at a specified
change frequency.
You need to specify the number of states for a picture display and the number must not exceed the allowable maximum.
You can define a picture for each state. At runtime, a picture display shows the picture corresponding to the state of the
monitored variable. The state of the monitored variable is determined by the state type and value of the variable.
