pressure_units 138D 单位 Field Device Variable Unit- Engineering unit to be displayed with the Digital Value representation, Minimum Span, Upper Range Value, Lower Range Value, Lower Sensor Limit, and Upper Sensor Limit. Pressure- Pressure of the process measured with respect to a reference pressure. 读/写 枚举 8
pressure_value 138E 压力 Field Device Variable Value- Digital value that changes magnitude with respect to time with no user intervention. Pressure- Pressure of the process measured with respect to a reference pressure. 读 浮点 10
pressure_percent_range 138F % 范围 Percent of Range- Variable that tracks the Digital Value representation with respect to the range defined by the Lower Range Value and Upper Range Value, for normal operating modes.

pressure_upper_range_value 1396 URV Upper Range Value- Defines the operational endpoint from which the Analog Value, and the 100% point of the Percent Range are derived. In addition, the Upper Range Value defines an operational endpoint which the alarms associated with the Analog Value, and the alarms associated with the Digital Value representation are derived. Pressure- Pressure of the process measured with respect to a reference pressure. 读/写 浮点 32
pressure_lower_range_value 1397 LRV Lower Range Value- Defines the operational endpoint from which the Analog Value, and the 0% point of the Percent Range are derived. In addition, the Lower Range Value defines an operational endpoint which the alarms associated with the Analog Value, and the alarms associated with the Digital Value representation are derived. Pressure- Pressure of the process measured with respect to a reference pressure. 读/写 浮点 32
pressure_damping_value 1398 阻尼 Damping Value- Damping time constant applied to both the Digital Value representation and Analog Value of the respective Analog Output. The units of this variable are always in seconds. Pressure- Pressure of the process measured with respect to a reference pressure. 读/写 浮点 8
