Deadband control tags monitor the value of any tag with a numeric value and compare the monitored tag's value to a low setpoint and a high setpoint. If the value of the monitored tag falls below the low setpoint, the value of the deadband control tag is set to 1. If the value of the monitored tag rises above the high setpoint, the value of the deadband control tag is set to 0. The drawing methods for deadband control tags enable the operator to set the value if it falls between the low and high setpoints.
The following drawing methods are available to deadband control tags:
