Dead-band interval properties

The dead-band properties allow sampling variables with respect to their previous sampled value. The dead-band helps prevent sampling values in rapid succession due to oscillation in the control system.
Property
Value
Description
Default dead-band-mode
None
Samples the variable when the value of the variable changes by any amount.
Absolute
Samples the variable when the value of the variable changes by an amount equal to or greater than the absolute dead-band value.
For example, if the variable value is 3 and the dead-band value is 1, the variable is sampled when variable value is 4 or greater.
percent
Samples the variable when the value of the variable changes by an amount equal to or greater than the % dead-band value.
For example, if the variable value is 10 and the dead-band value is 20, the variable is sampled when the variable value is 12 or greater
Default dead-band value
Free choice
Determines the dead-band value.
