vol_flow_percent_range 4051 Volume Flow Percent Range 量程百分比 - 跟踪与正常工作模式的量程下限值和量程上限值有关的数字值表示的变量。此变量的单位始终为百分比。 读 浮点 34
vol_flow_upper_range_value 4052 Volume Flow Upper Range Value This is the 20mA point. 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 the point above which all high alarms (both analog and digital) for the assigned process variable are activated. 读/写 浮点 32
vol_flow_lower_range_value 4053 体积流量量程下限值 This is the 12 mA point (Direct) or the 4 mA point (Level-Shifted). 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 the point below which all low alarms (both analog and digital) for the assigned process variable are activated. 读/写 浮点 32
vol_flow_upper_sensor_limit 404A 体积流量传感器上限 传感器上限值 - 定义量程上限值的最大可用值。 读 浮点 8
vol_flow_lower_sensor_limit 4054 体积流量传感器下限 传感器下限值 - 定义量程下限值的最小可用值。 读 浮点 8
